I was split between RPGs and strategy but reasoned that I like RPGs that have strategy elements and am not half as keen on those that i.e. only feature one player customisable/controllable character. I guess it all blends when you get to leveling and skills, but its always the "how can I best make my character/squad/party" that I like best about RPGs. I get tired of RTS' pretty quickly though as they are a) mostly about micro managing and b) so short sighted. I really like to have a grand startegy -be it planning a character for 30 levels of hack'n'slash or (even better) a world map to paint in my faction's colour.
