Single Player rts/battle arena type games?

[Yenni Brusco]

I was wondering if anyone knew of games with mechanics similar to League of Legends' casting system that was single player, or perhaps more casual. I'm also looking for games that might have a more torchlight feel, but both games are way more complex than some systems I'm trying to design and I've been asked to provide comparative games but have exhausted my resources for finding any.

By the LOL mechanics, I'm meaning the 4 abilities and them being cast-able and having extremely tiny cool downs but being limited by energy/mana. I'd prefer to find a game with these being used in a story-based setting, but any single player game with this simplified aspect of these mechanics would be a welcome suggestion for me to check out.

I haven't played it myself but Heroes of Newerth seems to be a good one.

Also, Torchlight feel? If you have already played Diablo 1 + 2 give Titan Quest a shot, it was one of the games I had the most fun with. I'd really recommend it.

Ah, I hadn't thought of Titan Quest. Thanks

I still need something even simpler though, I don't mind if it's a silly little flash game at this point even >.<
