Warioware gets old fast and I've never played Meteos. Polarium is pretty fun. I would suggest Kirby. I'm playing it right now and there are a lot of things to do; the main thing being to collect all of the medals to unlock secrets. You get them by finding them in the levels and beating time trials and courses where you can only use a certain amount of ink. It's challenging; I'm having trouble with the time trials. So therefore, get Kirby! |
