On that list, everyone should get Rayman if they haven't already. Splendid platformer. Zombi U is also worth it unless you prefer a disc version, just because of its uniqueness.
I could use some convincing to pull the trigger on Cloudberry Kingdom. I wouldn't mind a tough platformer -- I almost bought 1,001 Spikes but decided I'd wait until they patch in off-tv and fix the glitches. But on the surface, the randomly generated levels of CK just seems kind of soulless.
I'm also contemplating AC 3 or 4 but I didn't really like the little time I spent so far on 3. And Splinter Cell is just stealth right? I still haven't picked up Child of Light (not on sale) but I might enjoy that more after all.
Dam UbiSoft jumping off the Wiiu ship hard.
Nah. They still have Watch_Dogs and Just Dance 2015 coming at a minimum. I think they're probably just trying to intrigue new Wii U owners (due to Mario Kart). If this was an indication of them jumping ship, they'd be like EA who still has Madden 2013, FIFA 13 and Need For Speed on the shop for $60.
Also, Child of Light is in the Top 20 All Time Downloadable Best Sellers. Sales appear on par with NES Remix 2. And although I have no clue of the actual numbers, that's probably better than they anticipated.
