Comparing XI right at launch (pre-NA) to XIV ARR now. I would say ARR wins fairly easily.

The question is will it be comparable when it will be Zilart vs expansion 1. Zilart added littearly thousands of hours of content to the game. I question if XIV can do the same due to its design.

Another difference is in XI people were just getting to endgame when zilart launched for the most part. In XIV people are at endgame within weeks, and spamming what little we have.

So XI's longevity at launch was probably 4-5xs higher the XIV's currently.

That is where Old XI had it over XIV, XI had alot more longevity at its early stages.
