I predict the vast majority of people here saying that they are going to skip the game end up buying it within the first month of release.
Not me, though. I've actively said I'm going to skip Mario Party 10 and I'm not buying that either due to the amiibo DLC lock in of content. I've cancelled my Mario Party 10 preorder as well. I've skipped quite a few games for whatever small reason I can't live with. Thankfully money is a finite resource so this is good for me in the long run. (Who has money to buy $40-60 games all the time?)
This could've been Nintendo's attempt to bring some Super Mario Sunshine kind of magic back, but Splatoon seems lame. I expect 7/10 IGN, maybe 81/100 Metacritic and 35/40 Famitsu. And 2/10 from shinkodachi.
