I still wish they'd retroactively add cross-buy to this, as other indie games have done this (I got Whoa Dave free on 3DS for buying the Humble bundle and then when the Wii U version came out last week I got it free.)
BUT, that said, the Wii U version still has that Smash Bros. Arena mode coming, exclusively as far as I recall, and the 3DS version has the streetpass arena. They're not bosses, no, but the Kratos boss wasn't all that good anyway. The Battletoads boss looked amazing, though. It doesn't matter what platform you get it on, really, just buy it. You won't regret it. If you're an amiibo fan then there's literally no reason not to buy the Wii U version and do the amiibo Co-op or the 3DS version and the amiibo challenges. While the amiibo content lock isn't the best way to do things, the game is also over a year old and has three free expansions coming out for every platform, so I can grant a pass for them money grubbing a little for 100% optional content.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
