kind of a sudden and surprising realization for me. the WiiU hasnt spawned one succesful new IP. i base this looking at VGC WiiU's database. if there is a digital game i didnt think about, let me know.
there are only three games that can come to mind:
1- nintendo land, but that game is a collection of minigames based on a range of MANY popular IPs like mario, zelda, metriod, donkey kong, kirby and others. the only thing new about it is the title.
2- then you got hyrule warriors. which is a mash up of two existing IPS, The Legend of Zelda and Dynasty Warriors. even the name is a mash up.
3- ZombiU, but that game is the definition of a failure, because it wasnt even close to being profitable and has no sequal planned.
you can argue that techinically the first 2 games might be new IPs, but they are just based on current existing ones.
in constrast the XB1 and PS4 have a range of succesful new IPs. some small successes and some mage hits. like Watch Dogs, Transistor, Destiny, Titanfall, Driveclub and The Evil within. and thats when they are a year younger, next year there are also lots of new IPS that look like they can be successful, like the Division, No mans Sky, bloodborne, The Order, Ori and the blind Forest, Quantum Break, Dying Light, Evolve, Project Cars and others.
Edit: it seems due to my stupidity, i forgot that Watch Dogs released later on WiiU. and while it didnt spawn on the console (or contribute to its success in any way) you can say i am wrong.
there also seems to be shovel night, but i did say in my OP, right in the first sentence, that i am not aware of digital games. either way i stand corrected.
however, the thread paints the same picture, if the only successful new IP is a digital game and a miltuplatform game that saw zero success on the wiiu, you can see how bad the situation is.
