i would say its very unlikley due to the trainers intercepting memory adresses.on the other hand look at kane and lynch, how there is something built into the game preventing cheats, so you have to keep reactivating the trainer every couple of min.as your playing. it would be very lame if they waste effort into preventing singalplay cheats. i mean who cares if someone wants to cheat in singplay.achievments are worthless i think.i wish there were more games with built in cheats like saints row, gta, and such. it adds to the replay value of a game.
Agreed, just to let y'all know i only use cheats once playing a game the second time through for added FUN FACTOR!
I believe that Games For Windows LIVE is for the most part voluntary. You should still be able to play the game without signing in to LIVE (and if it does it for you, just simply sign out and start the game). This way, your game never makes contact with Microsoft's servers and you can use the trainer worry free.
Correct. Unless you care about achievements single player games can be totally played offline just never put in a LIVE account.
However Multiplayer LIVE games obviously require an account which is now 100% free for all PC features (xbox 360 still requires the pay Gold account but Games For Windows LIVE is 100% free)
