should I use 3D side scroller or 2D side scroller for a game like super meatboy?

I am trying something to create a game kinda like supermeat boy but please remember I am not an artist and I am 1 man development team. LOL this is a hobby on my freetime after school so with that taken into consideration am I more likely to find free common source license stuff for 3D or 2D?

I am thinking 3D right? plus I might need to use the special effects of the Engine to compensate for my lack of artistic skills.

I would use 2d side scroller with paper 2d. Since its sprites and stuff like that.
