Hi Sandro...
Hello Commander Ozram!
The challenge of playing in solo being too low (without taking sides) is a valid argument to make, although it might better be phrased as "the opportunities for challenge are too low in Elite Dangerous". It's actually something we are interested in looking at.
I agree with what you're saying here Sandro, but I'd think I'd go further. It's not only the opportunities for challenge that need to be increased against the AI, but appropriate an risk/reward put in place.
It's worth keeping in mind that even in Open, a slow network connection can prevent a lot of instancing, particularly if you're in a strange country where you used to send criminals.
The game difficulty has to be balanced on it's own in Solo.
Let me give you an example of where FD has recently regressed in getting this risk/reward balance right. The 2.3 changes to exploration payouts. One scan of a earth like or water world in the bubble now gives a commander 260,000 credits, enough to buy a detailed scanner, and then every subsequent scan gives over 600,000 credits. This makes early missions pretty much redundant, and this approach is pretty much risk free. It's also a risk free and relatively quick way to increase faction rep and level up to Elite exploration. And you can do this all in the bubble.
Now, FD was right in realising that exploration needed a bit of a buff. But they didn't consider risk/reward. Outfitting yourself for a long distance exploration trip with appropriate supplies, and flying away 1000s of LYs, and constantly risking losing it all is far more risky than hopping around the bubble and frequently selling data. It's the trips into the void that deserved the buff (the side with risk) not hopping around the bubble (the safe approach).
This change to exploration is a good example of why FD get accused both of ED being too grindy (which I'm not sure I agree with) and it being too easy (which I do think is the case). Because it's too easy to make money in a risk free manner hopping around the bubble. But the more dangerous, and perhaps more importantly, more challenging tasks that require more thought, don't have much higher rewards for time spent. So the tendency is to grind, because mindless simple tasks are just as rewarding as complex ones.
ED has to be made both more rewarding and less rewarding. More rewarding for challenging complex task, less rewarding for safe, mindless low risk tasks.
Whilst the game badly needs balancing, fortunately, it's not hard to do. Here are some relatively simple changes:
1. Reduce exploration rewards back to pre-2.3 levels, but greatly increase first discovered bonuses. Do the numbers so explorers outside the bubble make similar rewards to what they do post-2.3 (or perhaps even higher), but hopping around inside the bubble only gives pocket change. Aside from rebalancing gameplay this makes sense from a gameplay perspective, as it makes sense that new discoveries be rewarded many times more than just updated data. As more systems are discovered, the first discovered bonus could further increase.
2. Increase the skill level of the top NPCs, and give them engineered weapons, armour etc, but significantly increase their bounty rewards. Elite NPCs should not hold back, they should do everything except actually cheat. They should be the best your AI team can make them. Ensure that the bounties are such that an experienced and well equiped player makes more money taking on these top NPCs, even when considering frequent trips back for repairs, than grinding out low end NPCs. Even make Very Haz sites which are basically killing zones for any individual commander no matter their ship, that really can only be handled with a wing (and even that's difficult).
3. Ensure there's no way to do "free" stacking, i.e. counting kills for multiple missions, and ensure that bulletin boards don't produce a bunch of missions to the same destination, and perhaps to prevent board flipping exploits just don't show missions to the same destination as one already excepted, unless a player actually flies to another starport. Increase mission rewards to compensate for this, particularly difficult missions.
4. Get the "risk/reward" for cargo trading right. Don't just have a trigger that says pirates attack if you've got 2T of biowaste, but what, how many and their skill level should depend on what's in your cargo hold. A new player should be able to trade a few tons of low value cargo completely unmolested, but a Cutter stacked to the brim with Painite and Slaves should have wings of Elite pirate NPCs all over it all the time. The shieldless Cutter should be relegated to the dustbin of history.
5. Increase the deviation from the "Galactic Average" of commodity prices based on security status. High security systems, even with the items they export and import, should have relatively small deviations from the galactic average. Low security systems should have higher deviations, and hence greater profits, although low security systems will have more and higher skilled NPC pirates.
I know you're doing some of the stuff I've mentioned already, but I think you need to be more radical in making rewards more closely match challenge and risk. It's not a disaster if it takes someone a bit longer to save up for an Anaconda, they'll just get to enjoy he other ships more in the meantime. Reducing the rewards of stuff like in bubble exploration is reasonable if players have the option to do challenging things to get the rewards they're after.
None of these 5 are huge changes, indeed most of them are just mucking around with the numbers involved in the game already. Note when I talk about rewards, especially at the higher levels, it's not just credits but engineering mats. Making more challenging experiences, but also rewarding them appropriately (with not only credits, but high level materials on a consistent basis) will reduce the complains about grinding, and combining that with lowering the rewards of simple low risk activities will encourage players to challenge themselves, not just feel like they're grinding or just racing through the credit ladder too easily.
This post ended up a bit longer than I initially wanted to be, but I hope you find some of my thoughts useful.
