Just a quickie, I am looking to start a top down (no up/down axis) project that involves physics, such as gravity of the player pulling enemies to it etc. Should I make the project 2D (Its vectors not pixels) or 3D with a set camera up the top? Any advice would be helpful.
It depends on your level in unity! If you have just started it will be better to start with a 2D project. Now, if you think you’re pretty average in unity, I recommend a 3D project. After that, whether it’s 2d or 3D, in a game like this, it doesn’t matter too much, except that in 3D, you can add visual effects, 3d models, you can also play on the light, etc …
Hope to have helped!
Have a good day !
