Why care what "they" want? We - the Commanders - keep the servers running. I mean this attitude is just...so game devs are infallible or something and we can't give feedback? What if they didn't get it right? Was Power Play 1.0 a great system? No. Finally after YEARS of feedback they listened, and the game is now better for it.
We need a large hauler, yes. Something that holds vastly more would be great for the game, and let's face it - it makes way too much financial sense to NOT do it. The demand for ways to make Colonization less mind-numbing boring are ubiquitous. People would line up to buy ARX!
Other reasons.
1. It would be cool
2. New ships are cool
3. The bigger the ship, the morer coolerer it is
4. Hmmm I think that's about it.
There's actually several things that should be tweaked at the same time of launching the "supposed" Panther heavy hauler (assuming it's along these lines):
The barrier to entry for Sys Colonization should be higher, such that not every player is trying to do it right off the bat. Is this unfair? Well what's the barrier to entry for acquiring a FC? Is saving 5B credits something a new player can do right off the bat, and is that unfair they can't have it right away? No... so raise the sys colonization bar.
Making new claims for Sys Colonization should be dependent on more structures needing to be first built, prior to a new claim being allowed. Currently all that's needed is 25M and another outpost in the vicinity. But requiring more stuff... like a Tier 2 build to occur before a new claim, after the first system, will slow this down despite a new larger ship helping out the building speed. (Actually just say one's first claim is free, but after that requires one Tier 2 point to make another claim, thus requiring building for additional claims.
Tie Sys Colonization to player-owned factions, resulting in joint ownership of system expansion only. This will allow all players to reap the rewards of combined efforts to support their player-faction's expansion and growth into new systems (and fighting for control over existing ones). Raise the rewards from controlled systems so there's a meaningful reward to all the output of the controlled systems. Currently this is a huge miss with the recent faction re-launch. Sys Colonization should be more collborative and encourage team play.
The advent of player-faction feuding replaces the now-pacified alien invasion narrative. It should be "peaceful", but humans being humans, find another way to conflict over something (is war rather than peace really our true natue?)... player faction power play, not NPC's.
And/or allow for NPC hauling.
And/or allow for resources withing one's system to be alloted to builds within that same system. This is similar to how one economy's output will input into another's economy. Just allow for builds to be designated this way so it'll cut down on material transport.
Fully customizeable ships beyond the cutter/corvette class... but less than the current FC. Nothing pre-fab'd... let the players decide the mass and performance based on modules and size... and the shipyard (FC vendor yards) will produce it after a certain amount of days. This will satisify many player's itch for what ships are missing for whatever role from the game, and remove the Dev's as the blockers for spoon feeding us their ship designs. Just give us the mechanism for ship design in the game (chosing mass, modules, hardpoints, body style etc... and having that all translate into a "mini" mega ship design we can order.
Otherwise, it just comes off all just another time-waste for nothing in return other than one's name appearing in the corner of the system map.
