I haven't had a Nintendo handheld since the Advance, and ever since I bought my 3DS on Christmas I've only been playing Pokemon White 2. Bought it pretty much for that, and am super hyped for Pokemon X/Y now.
But I'll probably get Fire Emblem as well, since I've only read good things about it and it'd be a shame if the 3DS was just a pokemon machine. I've never played Fire Emblem, watched a few trailers only. Looks like a JRPG with a tactical grid for battles? Similar to Heroes of Might&Magic? Or am I completely off?
