Wow, WarioForums seems great! I've only played Warioware games and I own Wario Blast, but Land looks really fun! My favourite characters are Ashley (I'm even a mod on a Discord server of her) and 9-Volt and I hope I enjoy my stay here!
Welcome to Wario Forums @SniperGabe! Yeah, the Wario Land games are really fun, and you should definitely try them out at some point. Wario Land 4 may be a good one to start with, since it's a very relaxed, simple game which eases players in with a choice of difficulty levels, boss items to make fights easier, etc. But any one will work here.
