I like not having to pigeon-hole my games.
Take my latest favorate, Hearts of Iron 2, it's a 'realtime strategy' because it's a game focused entirely on strategy and it's in realtime, and yet, 'RTS' players would hate it and most probably wouldn't even recognise it as an 'RTS'.
Sacrifice, Hostile Waters, Battlezone 2, all some of my favorate games, and yet, none of them can be done justice with the crude monikers that the industry loves throwing around these days.
