The IPS screens are more colorful than the TN screens. I have a New 3ds Xl with a IPS top screen and TN at the bottom. Also, the view angles are much better on the IPS screens.
I really like the design, though I can't justify getting this one. I wish Nintendo would have continued using IPS screens. These are far superior to the TN screens.
I went ahead and got it. Tooth and Tail is a lot of fun so far. I like being a commander in the game and moving around dodging bullets (a different way to command troops vs traditional strategy games). I think the bundle is worth it, and I'm also interested to try out Endless Legend.
