I wish we get to see Ratchet wearing winter suits in ice/snow planets. (I mean, how the heck did he survive the cold in the first game shirtless and in ToD only wearing his pilot suit?)
(This one is long) Granted: The Snowsuit is actually a fully fledged Gameplay feature. Ice has always been part of the first levels. Walking in ice zones would make you freeze to death after 12 seconds, unless you find any warm spots to recharge. Once you get into the first really cold level, you're required to buy a snow suit which makes it possible to stay in the cold. It costs 100 "Ice Diamonds" though, which are found in the thundra on the ice level, and the only way to acquire them is by going out and hunt them on a huge map while you need to manage the extremely annoying freezing mechanic. Afterwards you finally think you're done, but in GC fashion, a second, colder level needs you to buy the second level Snowsuit using 100 "Snow Rubies", which are acquired like before. This time there's annoying enemies too, that push you out of safe zones.
I wish out of no where IG reveal a second game in DL fashion, dark, edgy, and full of explosions, but with a real deep story and Objective, all in PS4 glory!
