Rugby League Riot is the ONLY keyboard operated Rugby League PC game (that I know of), as a throwback to a classic - ARL 96. Try it out in this limited demo. There is an instruction video to the right which teaches you how to play. If you like this game then the full game can be bought over at Steam!
