Here's a list of 2014 multiplats not found on Wii-U (yet...I think a couple are coming over soonish, like OlliOlli and Chariot). Not all of these are system sellers - very few of them are - but most of these do add value to a possible future library for a prospective purchaser. (Ie, "I'm not going to buy a system for Alien Isolation, but when I get the system that will certainly be a game I buy for it.") Bolded are the games I played in 2014 to some extent (basically this isn't just a list of unkown titles I just found on the internet). This list excludes exclusives, console exclusives, company exclusives, and mysterious games I've never heard of the internt claims exist. =)
