unlicened mods don't cost, but I do sence people who want to mod half-life 2 talking to valve about "selling it" like Rag doll Kung Foo did. I too miss when all you needed was the base game, then all the mods were yours.
Oh ya cs:s is a mod of hl2 not a full game. You are crazy to consider it a full game with all it's bugs almost a YEAR after it's released and only one model per team. Also it isn't as good competitive-wise as cs1.6, and did i menction that valve hasen't even ported all the maps from 1.6 over? Valve is not a very professional company. Now tell me, does source have any new guns? No. It only has de_tides, a map from czero, and thats it for new maps.
CS: S is just a ploy by valve for you to think you are buying a "full" game when you are in fact buying a beta mod that's not even finished yet.
