To give credit to CS, Its been out for 7 years at this point, and they have maintained updates for the core game. In addition, they have not locked any "critical" functionality behind a DLC, but rather, the DLCs just gave the game a different experience.

As many hours as I have dumped into the original, I'd feel MUCH better paying 60$ for it, as opposed to half of the AAA crap out there, where I might be lucky to get 40 hours of gameplay.
