Hardly surprising that the sales have been soft since launch considering the shocking user reviews. The game is pretty good, but when it barely runs on most users machines people are going to either keep waiting for it to improve or write it off forever. All the die-hard fans who are even interested in the endgame content already have the game.
You can put in a buy order at 0.1 for a share worth 100. You’re dreaming, but you can still do it. Don’t think it really qualifies as abusing the system.
Probably the most exciting part of the trailer is that it all but confirms multiplayer which was probably the biggest missing element of the first game.
