I'd probably advise this as well. Chaos Edition contains 3 teams, one of which is non canon, and completely made up (so not in table top version), and Underworld are fun, but kind of underpowered. The only real useful one is Chaos Dwarves, but they're basically wrecking balls. So up to you if $10 is worth playing that team.Get the legendary edition. Far as I can tell the chaos edition is just a couple more teams, and a stadium. The LE is a great deal. After you get the hang of it the game is addicting and a ton of fun.
