Since the early 90s of Fallout ONE, the Pipboy was brilliantly designed to buy and sell items. In this mobile game, you guys have created the exact dialog design that your 3D engine (Unity?) can't handle. Side-scrolling lists of images. It doesn't work. Please consider bringing back the traditional warm fuzzy dialog from Fallout ONE through FOUR where one deals with item names, we move items in stock from the left to the right, see the total money generated tally up, then press SELL. One big nice transaction with minimal scrolling, minimal artwork, thus minimal artwork rendered on poly performance problems.
You could also factor in ALL your other dialogs with tabs just like the original. Why design something different when the franchise got it right 25 years ago?
