What rpg system would you use for a 60+ session fantasy campaign?

I still feel RM has one of the best class and level system implementations for that reason.

By the time you got all the 2e Companions there was something crazy like 50 classes, too. Pretty much every imaginable niche had a class or three (one per type of magic) covering it.

Well, the last time I did that, I used D&D 4E, I would do so again (especially with Virtual Table Top support).
Alternatively, I might make my homebrew Arcana Evolved, which is where I apply 4E concepts to the Arcana Evolved/Unearthed classses and mod from there.

AD&D or BECMI. First choice. Easiest choice.

This seems like a strange thing to ask on EnWorld.

5E D&D or, if I could get away with it, 2E.
