Disabling Game Saves and Trophies/Achievements

In an effort to deter game completion by using cheats, Rockstar has implemented drawbacks to using cheats in their recent games and keep them as a "for fun" option. In GTA IV some trophies/achievements were disabled when certain cheats were activated. Red Dead Redemption followed suit and also disabled autosaves plus manual save files were marked with a (*). The only way to continue gaining trophies/achievements is to load a game save made prior to using cheats. GTA 5 will likely have similar restrictions.

Note: Cheats are different from mods. Cheats simply alter existing data in the game. They do not add objects or gameplay features. Mods are left up to you - the fans - to create after the game releases.
