I’m not so new I backed the game back in 2015
Look, MoleHD mostly answered for me, but notice how i never mentioned other games in my argument (unless asked for a list of them in one instance). Because comparing SC, which is currently between pre-alpha and technological demo stage, and fully released games is worthless.
So you decide to go on the "SC is a full game and i'm comparing it to other released games" approach... I could pick so many examples in your laundry list of arguments (by the way, dont try and gatling-shoot your CiG talking points..), lets try just one. You talk about multiple SRV's compared to ED single Scarab. Alright. With the Scarab, we can explore (with various scanners), with fully associated gameplay loop (getting money and materials out of it, and elite rank), collect engineering materials for upgrading our ships, blast things out and collect more things for various surface missions, which are proc gen by the way and in vast numbers.
Let's see what we can do with surface vehicles in SC. Hmmm... Not including the meta-game where you try and fit a Nox in a Cutlass cargo bay (good luck achieving that !!) without having the physics engine throw a fit and your Nox into orbit at instant warp speed... Not including "taking screenshots for the subreddit" which is also not gameplay proper... See where i'm coming here..
So lets be serious. The current situation of SC is, there is no game. It's a patched-together Cryengine mod that tries and work around its own limitations, with disastrous side effects that will never be fixed, in any way. There are very few gameplay loops, space trucking being one, and even that is very embryonic to say the least. So how much game content is there ? Not so much at the moment. You can climb in my Retaliator and go shoot pirates from a turret. It's a good 15 minutes of honest fun when you finally reach that point. You can try and battle 30K errors and trade cargo, with a completely static economy inside one single system. You get over it quickly. You can try and go mining, again avoiding 30K errors like a ninja, granted that's maybe the only complete game loop so far. You can try and do one of the handful of hand crafted missions, but these are terrible, buggered messes that end up with that terrible FPS mission where the "AI" is just brain dead (and respawns, by the way, since there's a single location for everyone). You can try and go gank newbies or bounty hunt the gankers (it's a lot of waiting and frustration due to multiple game bugs, starting with the refuel / repair that's either not refuelling, or not reparing, or both...) but that's not really "content" yet.
That's it. You are trying to sell us a glorified, buggered Garry's Mod as the new BDSSE whereas most of us have played NMS, ED, X-series and others. Expect less patient answers.
