God, really? I can't take those for more than 1h at a time usually. Except Chrono Trigger I guess. Any recommendations?
I admit, they're all an acquired taste in many ways but once you get into it and stop minding the complexity in some of them, they can suck you in and move you out of time.
Other classics are Dragon Warrior IV for the NES, and Phantasy star IV for the Sega Genesis. No need to play the previous ones.
My other recommendation is using an emulator to give you unlimited money and experience. The gameplay is ruined, but the storytelling is more fluid, and you'll save many hours.
