If you don't like EA Rugby games, don't want to pay to play or simply want to challenge many human players, then you should try an online management rugby game.
The one I play is Rugbymania (RM):
Rugby Mania - Online game - Manage your virtual rugby union team and it's great.
Other exists such as BlackOut Rugby.
RM is a long term and slow game but it's very rewarding to see its team improves weeks after weeks and compete to become the best in one's country.
