That’s the problem, the game is practically unplayable. I start a new game, something happens to cause the game to crash and it’s time to start another world because it’s corrupted.
Sounds like you should head over to the support section, read the Sticky threads, and start following instructions.
How long does it take to get out of alpha phase? 10 years?
Average for a AAA studio with a near-unlimited budget, and several hundred developers on the team is 7-9 years.
TFP is developing a game much more complex, with a team a fraction of the size, and a very limited budget.
So yeah, they're doing just about right. It's perfectly normal.
The difference is, You won't even hear about the AAA studio's game until they're just about ready to release it. When internally they're already in Beta. With This, and other EA titles, you get to play the game before it's done being made.
This was explained pretty clearly in the Steam EA FAQ that Steam made you read before purchasing the title.
So what I suggest to you, is to lose the attitude and seek some help with your issue. It is your issue after all. I was playing this title on a PC circa 2011 just fine. Sure I had to struggle some with the configuration and settings, but in the end I took it from maybe 60 FPS, to 110FPS solid.
