Is there a list, or a way to search, of games like Geo Wars that had a specific update to take advantage of the iPad Pro?
I don't know. When I was first got my iPad Pro 12.9" I was only focusing on games that took advantage of the extra horsepower and screen real estate. There is the 'apps for iPad Pro' icon on the AppStore. I have a couple of games that have taken advantage of the iPad Pro when it first came out. Implosion - which is great on the iPad Pro (and a MFi controller) Asphalt 8 Games I can think of that are only on the iPad as opposed to the iPhone X-Com Star Wars KOTOR
