This isn't really bothering me as much as it use to... I know the game didn't sell well the first time around, and a re-release means that there's hope of updates instead of it just being abandonware... It does suck to have to buy a game twice... But you don't have to. I've still got the game on my PC, but I will repurchase it if the game is updated instead of just being an exact copy of the pulled version.
Just hope thats the way it goes.
The only thing that really gets me anymore is if a Dev throws ads into a previously paid game, and adds an IAP to remove the ads, or if it's a big game, that we all know sold well (Tetris comes shooting into my mind like a shotgun blast) and gets pulled to be re-released... Or a full premium game goes freemium and gets rebalanced (Major Mayhem type freemium movements don't bother me one little bit...)
Anywho, if you don't have this one yet, it's worth picking up. I enjoyed it quite a bit back when I had a 2nd gen.
