To be honest, looking at both screenshots Rugby Challenge looks as if it has the better graphics but the whole crowds and stuff on the Rugby World Cup one look better, just because a game has licenses doesn't make it better, it may make it more sort after
but I think both games are worth a look at, It's not like you cant send one back if you don't like it :)
Rugby is up and coming over here in the states. there are more and more states every year that for senior teams, high school teams, and college teams. I and most of my friends think xbox needs to release rugby challenge for sale in the u.s as of now you
can only play it if you live in australia or all of europe. Just trying to see what other people have to say about this.
