The first game was a technical and artistic marvel on Vita (especially on an OLED screen) back in 2013. It really showed how much potential Vita's hardware had if an early title like GR could achieve something like that. The only problem for me were some of the controls in a specific level that ultimately made me quit the game. But until that point i had a great time with it.
GR2 was even more beautiful and frankly one of the most criminally underrated games in terms of art style. Controls felt much better with a dualshock and i enjoyed it more than the first one but i also never finished it because i got sidetracked by other games. But i plan to return to it one day and start a new game.
