I'm a gamer like most people here. I like zombie killing games.
So Source mods keep appearing on MODDB, sometimes just rehash of old ideas, though there's occasionally a great one. This makes me wonder what would happen if Valve ever introduces Source Engine 2.
Source Engine 2 would presumably have HDR effects, more bloom, better physics, better graphical detail.
Maybe Half Life 2: Episode 3 is actually Half Life 3.
