I think there are some brushes in the 'texture' category, there's also a way to copy and paste images into Krita and make one color transparent, I do that sometimes! Filter > Color > Color to Alpha
So maybe you could find a paper texture online and make it transparent using the filter
hmm maybe paste one of these onto a new layer of your drawing? https://unsplash.com/s/photos/paper-texture
I think it just depends which games you would play more! I think PS3 seems to have more fun 'casual' games, and XBox is better for adventurous games... I don't play consoles a lot though! Personally I'm biased towards the PS3.
