easiest first game?

I’m very new, right now just playing around with levels and tossing around ideas.
I am wondering. for my first game should it be first person? side scroller? Top down?
I basically want to make a good game, but not remaking pong.
I am thinking first person would be the most detail intensive.
What do you think?
Any other ideas?

Also should I make my first game free?
Any help would be awesome!
