Eh, that depends on the definition of "loving" and "sucking". The only game(s) I can think of that I'm no good at all at, and still enjoy playing somewhat, would be DotA 2
and all the other similar titles. The thing is, though, I'm not utterly
horrible at them. I'm just not good at them. And I can't say I love them either. In fact, I usually kind of hate them. These games are great fun if played with a full team, but they can go fuck right off if there's more than one random guy on my team. And if I'm on a full team, I suddenly play way better than if I play solo for some weird reason, so then I both enjoy the game and play decently at the same time.
Otherwise.. if I enjoy a game, I'm usually fairly decent at them. That includes genres that are notorious for being really hard to get into for a beginner as well, like RTS and fighting games. In fact, I was a top 100 player in the original Company of Heroes
, and I go to fighting game casuals on a regular basis, so those are probably my favorite multiplayer genres overall :V
edit: OH, and one more thing. Horror games. Man, I love the way horror is done in games. To the point that I can't fucking play any of them. I never get scared at horror movies, I've never played an actually scary survival horror game for more than one hour before never touching the title in question again
