I agree that still seems too complicated. They're selling 3 old games together as one product, and the DLC for two of them together as one product, and then I guess you're meant to run one .exe no matter what, and then the in-game store sells items and such.
Is there any game that does this?
I guess it's an improvement over what they had before, so that's good.
The "deluxe" content doesn't seem to review well on Steam, so I suggest skipping that, and the "world of assassination" pack is 3 old games, so I suggest not paying $70 for that. Get that one on sale 50% off sometime.
