I don't even know if I would have liked it but I was initially enthralled by Ricochet, the Goldsrc game on Steam that uses the engine Half-Life 1 ran on. I think it was free at some point because it just appeared on my game list when I installed a bunch of Goldsrc games. The multiplayer was dead, with only a few bot servers active and the bots were too good to be fun for a beginner. I remember reading, I think on the escapist, that there was a rumor that Ricochet 2 would be the first game released when Source 2 comes out, but I doubt that now that it appears Left 4 Dead 3 is a thing. I would really like to see a Ricochet sequel, just so I could play it and see if it was fun or if I was just blinded initially by curiosity.
I also liked Tomb Raider's multiplayer when it worked, but I do think it would get old pretty fast, I just never got the chance to play it enough to let it get old.
Oh, and I have recently been playing through Max Payne 3's arcade modes again and I wish the multiplayer was more active and less crappy, in that I wish it had PC features instead of Rockstar's really bad lobby system that makes it impossible to find populated games.
