Well, ever since I picked him up, England's been my favourite to play. :'D Mostly because I've never played a character who was this outwardly cranky or as capable of being a bastard when they want to be as England is, so it was a fun and refreshing change from the outwardly dorky/derpy nice guys I usually play. |D Also, I am a history geek, and playing England means I get to find out and use crazy amounts of stuff.

Also? It's kind of really fun thinking about and expanding on the Hetalia concept. Like, matching up bits of English history with just why England as a character is the way he is is just. Really interesting to me. And trying to reconcile bits of this history with his personality and heeee I'm a geek and I love doing it. ^^; Also? It's hilarious fun playing someone this tsundere, which I've never really done before. 8D

THAT SAID, I also tend to favour, at different times, Ten for the crazy Time Lordy fun and because I can do anything with him pretty much, so he's really versatile for plots, Pearl for being cute and because I think it'll be interesting trying to depict her growing up, and Lyle because... well, he's Lyle and ilplaying him, I need no excuse. :|

... come to think of it the only one I never show favouritism towards is Alle, sob.
