Brag: I've been playing Mario Kart 8 for awhile now at home. Not for review or anything. Just because. Don't tell Nintendo, but I may have let my family play a bit too. They're also probably bragging now when they shouldn't be.
I had no point in telling you that. I just wanted to brag.
You can play Mario Kart 8 at GameStop on May 17 and 18 as a sort of preview, well before the game's May 30 launch. Over 2,700 store sill be open for a test drive between noon and 4 p.m. local time. GameStop has more details on the event here.
Those that pre-ordered Mario Kart 8 will get an exclusive double-sided poster at the event.
