It is, but Blood Bowl Team Manager is just a card game based around it. Really quick and simple, but a hell of a lot of fun.
My group has actually just started playing Necromunda a few weeks ago. Loving it so far, but my gang is taking a beating like you wouldn't believe!
Have got MGS Risk too - it's actually not all that great compared to LoTR and 2210, but it's still worth giving a go if you've played a lot of the other versions.
I haven't played Axis and Allies, but your best bet is to go somewhere like
boardgamegeek and take a look at what's about.
Where are you, btw? If you're not too far off then maybe we could set up some kind of introductory session to Risk or something?
