Seconded! I recently went back to the vanilla game and am playing through it trying to get 100% completion. It's very well designed and well balanced as well. Whenever I find myself low on health or ammo, there's usually a fresh box right around the corner, with plenty of secret areas to discover that are creatively hidden. Above all, it's just plain fun!
