1.0 was a drastically different game. It was more world less game. Very focused on selling you the world and giving you a sense of belonging and realism.

Chances are the original concept would be spinning in its grave from things like lockouts, mounts other than chocobos, cash shop, glamors, glowing weapons, unweighted animations, combat speed, heavy instanced content focus...

All in all 2.0 pretty much went the opposite direction for a good amount of content design focusing heavy on the endgame and leaving the start and mid game to mostly rot.
