Do whatever you want. I have a backlog of ~15 projects I constantly switch inbetween whenever I get burned out.
It’s much worse when you end up being burned out on every project, but it’s okay otherwise.
i recently discovered that psx games were getting more popular than 2d
I don’t trust such blanket statements. Firstly, I think you mean PSX-styled games. Secondly, they have been “hip” for many years by now, and are mostly an excuse to put little effort in modelling (just drag & drop a PSX shader and voila, “work”). Thirdly, real PSX and 2D aren’t mutually exclusive.
People have been predicting the supposedly inevitable death of 2D games ever since the 3dfx Voodoo. While there are ups and downs in popularity, that’s not really a reason to follow.
