More curious to see what Source2 has to offer than L4D3. HL3 should be the main focus at this point, its been on the back burner the longest. Not to mention the Source Engine is definitely showing its age these days.
Will be the obvious minority, but I'll skip on L4D 3. Have the previous 2 versions; fun as they were, it was enough. These days it's hard to find a decent server with people that just want to play and have fun, instead of this constant nerd rage spaz outs.
