There is noticeable slowdown in War of the Lions but I wouldn't say its as bad as you're making it out to be Necro. I mean the original had a bit for some of the more extravagant attacks but overall, I would say its acceptable. I mean to compare it the PSX port of Chrono Trigger is blowing this out of proportion a little imo. I agree its shoddy programming on SE's part but I feel the overall package outweighs the problems.

Overall, I felt it was fantastic, the cutscenes, the new translation, the extra missions and hidden secrets and props overall quality in terms of story, game mechanics, and presentation.

My only complaints are minor: The slowdown issue which has been addressed already, the attainment of certain high level gear being restricted exclusively to online play, and the removal of the spell/special technique chants in-battle. I really loved these little nuances and having it removed was a bit of a let down, but overall I still feel the overall package is quite good.
