well, i suppose it depends on what kind of player you are. i prefer real time games, and sadly what Morphling has said is true; there aren't many choices to do in real time other than strategic warfare. i'm hoping there's something more for it down the road.

the idea of it just appeals to me though, all about how quick you can think under pressure in limited time. it's more real to me. while turn-based games let you plan carefully what to do next, which eventually anyone can accomplish, real time tests your nerve and reactions to how you can think up devious plans when the enemy is already attacking.

against computers it's lame, but multiplayer is where RTS really do shine. For example, it's totally awesome to wipe out your best friend's Britons when you flank them at their base and wall them in with towers and archers while they still haven't even collected enough resources to feed an army yet.

again, it's all the kind of player you are. that's just me.
