I am thinking about getting a mifi controller for my iPad (mini-2), and I am not really up on what games support controllers and if games that do 'support' controllers actually play 'better' with them. http://www.bestbuy.com/site/steelseries-nimbus-wireless-controller-black/4860800.p?id=bb4860800&skuId=4860800&ref=212&loc=1&ksid=eac49e43-0fe7-4008-9fbe-d907eeb55ba4&ksprof_id=16&ksaffcode=pg49085&ksdevice=c&gclid=Cj0KEQjwid63BRCswIGqyOubtrUBEiQAvTol0TpX3FXh3SzTfKuD7hf8qG6GdMMa7cebh70ck9mbaY8aAjIS8P8HAQ This is the controller I am thinking about getting. Are there better ones available, or is that a great one as it is? Also, how does one determine what games can be played with controllers? It's not listed in an app description, is it (as a hardware feature)? Is there a website or app that keeps an updated list of compatible games? Will all games work with a controller? ..or just some? Example, Terraria.. While I want to like this game, I consider it to be unplayable on iPad due to the controls.. Every time I play this game, I end up rage deleting.. Ok, so I am mainly just brainstorming - but any tips would be awesome..
