Viking: Battle for Asgard - Should i buy it?

No.

No!

edit: hello fellow Raziel :D

1) If you have to ask whether or not you should buy a game, don't buy it.
2) When thinking of buying a game of limited entertainment value, consider how many hours of fun per dollar you'll be getting out of it.
3) If you want a game, but not badly enough to spend money on it, wait until you get it for free (or close to that).

Personally i would say yes however it depends if you like the style of the game. At the time i played it i enjoyed it because of the graphical style and the HUGE battles. I never had problems on the PC port but it doesn't have a lot of option that most ports have.
