I never liked Mario 64 that much but that's mostly because I wasn't a fan of the way stages work. I wanted a 3D Mario that was more straightforward like 2D Mario was back in the day.
The game did control better than any other 3D platformer for the next 2 or 3 years though; same deal with the camera too.


As for Half-Life, I really need to go finish it...
I was enjoying it, I just kind of stopped and never continued... （ ´,_ゝ`）
