I think the only games that captivated me for the longest time and that I played a ton and not because I felt I was forced to because I'd payed for them were Pokemon sapphire on the gameboy advance and oblivion when I first discovered it on the xbox 360. I remember finding oblivion for 10$ in the discount bin at a Zellers (These stores don't even exist anymore). It was one of my first RPGs and it was the best thing in the world to me at the time. After I played oblivion, I bought skyrim when it came out then elder scrolls online and I've just recently bought morrowind.
