This question already has an answer here:
I have a cluster situation. I used to DM Advanced DnD a looooong time ago and with life I gave it up for other things. Well my kids want to play DnD and want me to DM.
My oldest son went to a books sale and bought me bunch of 3.5 books, a WoW RPG book, and a Pathfinder.
My middle son is playing DnD 5.0
The dilemma is which route? I played 3.5 and like the customizability and freedom 3.5 brings, on the other hand its a old system and I think Pathfinder still follows it but Wizards no longer supports.
On the other side there is the new 5.0 but I don't know much about it.
My friend wants to sell me his 4.0 but a lot of people said BAD JOO JOO.
So anyway, I was hoping someone could give me some insight on the differences and what they would recommend.
