The wario series has unfortunately fallen dormant in recent years. The warioware series hasn't seen a release in almost 10 years with the release of warioware fit (game and wario doesn't count).
Wario land also hasn't seen a release for 10 years. With the release of wario land shake it in 2008.
Both of these franchises have both mostly been critically and commercially successful. I think both are due a comeback.
Does anyone have any thoughts on the future of Nintendo's most beloved character wario.
