I completed the first summoner as it was my first ps2 game. It was a decent experience and I liked the world lore.
When this game was released I was very excited to continue exploring the lore, but, at first, I was unhappy with the change in the playstyle, which became more action-oriented and without a party.
However, over time, the game started to captivate me and I found it better than the first one. But, perhaps due to the amount of games I already had at the time, I shelved it and never got back.
If I could go back in time, I would finish it. But nowadays, with the limited time imposed by adult life, I don't think it's worth it.
