When I was getting more serious into gaming, I purposively decided that I wouldn't go buying up a lot of games quickly for a couple reasons.
The first was that I already don't have a lot of space so I don't feel comfortable buying and keeping a lot of games around. Even now, most of the games in my collection are at my parents house (I have my PS4/PS3, Wii U - which is packed away, GameCube, DS, and SNES Classic here at my apartment). I love purchasing compilations and mini consoles since you get more games that way and it takes up less space. I'll even buy the occasional digital game here or there if it's for a good price.
The second was that even though there are a ton of franchises and consoles and I would love to get into (for example, I don't own a Genesis, NES, N64, Dreamcast/Saturn, only a few Xbox things), I've held off on diving into them because I felt like spacing out my purchases would help reduce burnout for the part of me that does love collecting. I figured that if I space out discovering new things to love about gaming then I would be happier for it in the long run? I dunno, it's a little hard to explain.
