Why? It is because we still like the older games and want to play them again. Xform is doing this for us unlike pretty much all other shockwave director game companies who just forget their games and leave them lost forever.
You didn't got my point. They already did alot of remakes and remasters, but when will they do a ACTUAL game again? They already have money, they are done with remakes (except burnin rubber 4, it's filled with bugs.), they can actually make a new game. Not a remake. I hope they will.
