I stumbled across a game on Kickstarter the other day, and it's beautiful; Hex Heroes is, in their words, a Party RTS (or par-tee-ess) for the Wii U, with a PC version also in the works and music by Grant Kirkhope. It uses the GamePad to bring a new depth to the RTS genre; one player on the GamePad does your standard construction and RTS commands, while up to four people on the Wiimotes control units that gather resources, explore, fight enemies, and so on.
The trailer they released doesn't show the prettiest game; it was thrown together in a matter of hours, and as such the models are rough. However, the finished models they've been showing in Kickstarter updates have been gorgeous, and what the trailer does show is the innovative kind of game that the Wii U was made for. It also contains a lot of cameo characters, such as Shovel Knight and the Game Grumps crew. It's nearly funded (73k out of 80k at the time of this article) with 24 hours left in the campaign.
Jump inside to see the trailer and maybe throw them some support!
