Yeah i do forget that RTS can be sadistic to you. Goddamn Pikmin the first of my RTS sufferance. But yeah RPG and RTS are probably the most thought consuming in any given situation. So many things to think about. Doesn't help if you have slightly eidetic memory for games.
Mostly RPG in my opinion, it's all strategy in the fights then you gotta figure out how you are gonna play the fight level the character and all that type of thing.
