Not seeing game I would like to play. Lots of issues and after five years it is good question if they can even solve them.
The problems are solvable.
For all my criticism, I'm still of the opinion that there is little or nothing in what CIG have promised that is undeliverable. I just do not believe that CIG are capable of doing so without compromising the vision of the game. More specifically, the game engine they have selected with likely require more work and modification to get around certain inbuilt roadblocks and then will require further work..
All of which comes down to "solvable, with enough time and money"...which then runs into the "it looked great in 2012, it looks OK now and it'll look downright primitive when it launches" problem. Which <sigh> will take more work, more time, more manpower to fix.
Technically speaking, though - I quite liked the demo. The "PAVS". Sure, it had issues, but, with enough care and work and time and money invested, I could see it being a game I would eventually buy.
The problems I would have aren't technical...those can be solved especially if CIG don't need to worry about servers or netcode too much. The problems are with the gameplay. This is supposedly a mission in the second third of the game. Why am I still spending so much time walking along corridors? Why am I taking 30 minutes to go from mission "start" - in the bed - to mission objective? Sure...the demo spent some time simply exploring the ship but come on....a freeplay exploration mode would work just as well. The problem here is that quite a good bit of what was shown simply isn't necessary and isn't reflective of how the game will be played. I do suspect that the suspicion that the character was deliberately kept to a walk, and made slow deliberate movements and lookaround to ease performance issues has some degree of truth. And I've already said quite a bit about the flight model.
So - technical issues can be solved (potentially, anyway), but gameplaywise, it looks like somebody somewhere in CIG made some very questionable choices. Artwise, the games graphics are aging...the backgrounds and ships still look good, but character models themselves are really starting to look bad.
All of which bodes ill for the game because the genre isn't quite as empty as it used to be. Since 2011, we've had several COD games, ME, DU, ED, Space Engineers and more all covering ground CIG hopes to cover with SC or S42. The demo here shows nothing unusual, nothing innovative, nothing groundbreaking, nothing special.
So....a potential "buy" from me, with the proviso that I'd wait till it was in the bargain bucket.
