Game Maker is good for 2D and is easier to learn in my opinion. Its possible to use it for 3D but I haven't bothered to figure out how.
Unity is a better more complex program overall that is good for 3D.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
So there's a steep learning curve.
Something like Game Maker or Engine001 is probably easier for creating a 2D RPG.
