You know, saw the 91% yesterday and shoved all that DLC in my cart and hurried the hell up and paid for it while it was still that price.
Is there any way to disable the 'cheat' dlc that are really early unlocks of things that you unlock during the gameplay anyway? I really dislike Facebookizing of regular PC games like this and I wish that sort of pay to win DLC was very clearly denoted.
I know some other games like Magic do this crap too.
If I'm just stuck with it now then I'm kind of annoyed at that. I don't mind trivial cosmetic DLC but I don't want cheats and shortcuts.
I had the same problem. I really enjoy challenging games, usually I play on the highest available difficulty, so I was really pissed after I saw I started game with 8 lvl, $200000 and probably one of the best car in my garage, which could be unlocked further in game.
To disable those pesky DLC you need to delete a certain files in the game directory:
1E6323E1.dat - Gold Top Dog
576E446C.dat - Silver Top Dog
E58008F5.dat - Red Envelope Pack
AC8D6F78.dat - High Roller Pack
Delete them before you start playing campaign. You'll need to restart and replay if you already receieved bonuses from them.
