i have played the GBA version of FF, and it was superb. the difference with the PSP version aside with the visual upgrades. it's that it was made more challenging. when i beat the first boss of the game and went to the first dungeon to fight the first optional hidden bosses, i beat them all while i was atleast in my mid 20, level wise. in the PSP version, i was in my 30's when i was able to beat the first optional bosses. i finished the PSP version with all my characters in their 80's. the most challenging part of FF (as you will notice that is the case in every FF you play), is when you fight 2 of the MOST powerful hidden bosses in the game, Omega ( 35,000hp) and Shinryu ( 35,000). Bring on FF7 to the PSP darn it.
Another remake of final fantasy one. Great. No, really, great. Final Fantasy (one) is a great RPG, and age hasn't hurt this title too much. You do the same things you (usually) always do in the earlier FF's - get crystals, level up, save someone, level some more. This formula works, and it works well on the PSP. The biggest flaw with this version are the graphics. They're definately a step up from the GBA version, however they are still 2D, and we deserve a 3d FF. For me, FINAL FANTASY III on the DS is the best handheld FF ever, and I cannot grasp why SquareEnix didn't take the extra time or effort to give us something similar - especially on a more powerful system like the psp. Regardless, this still is a great game and definately worth a rental for the casual rpg-er, and a purchase for the hardcore. B-.
