I'm not that far in the game yet, I'm at Djose Temple. So I haven't been properly introduced to Rikku yet I guess. So far, gameplay wise, I'm loving all the characters. I love how you can exchange them during battle.
The most useful characters to me so far has been Lulu, Wakka and Kimahri. Lulu for her spells, Wakka for his dark spells and far reach weapon (ball!
) and Kimahri because he's super strong and can tank pretty well with all that HP. Auron was good to use at first, but Kimahri became his superior at some point.
The characters I've enjoyed less (still gameplay wise) has weirdly been Tidus and Yuna. Tidus would be more useful to me if he actually learned some spells (then he could be more like Cloud/ Lightning and be 50/50) but now the only useful thing about him is Spiral Cut and that he knows Haste. Yuna is my only healer so that's good about her, but even though she now knows Life, she's just so... weak. Her HP was stuck at 520 forever, but that was actually my bad as I messed up her Sphere Grid in the beginning
I've tried to keep her in battle to fix the damage and get her back on track, but she's still mildly behind. Her summons are good, though. Thanks FF for finally forcing me to use summons so I get used to using them
(But thank you for putting in that 'press select to skip summoning cutscene' in XIII because summoning cutscene in FFX is like... o well better go get some coffee)
But STORY WISE *ahem* I think I'm just a bit of a deviant here. I absolutely love Wakka. I think he's awesome. He's like that semi dumb brute type you just gotta love. He's got HEART written all over him. I loved him from the beginning (even though his hair is stoopid). Lulu is awesome in battle (and her voice!) but what's with the clothes?!?! Tidus - not as annoying as I feared. He's growing on me. Yuna - a sweetheart, but I hope she gets badass soon because she's just too
nice Auron - hawtness, love love. But he's becoming too much of a cliché to me right now, so. Kimahri - when he tried smiling
OMG
I think he's my favorite battle character, but character wise I think he needs more love.
Others - I lol'ed hard at Seymour's hair, but I think he's a good character. Obviously has a thing for Yuna. Dona is enjoyable, but again - the clothes!! Ich. And what was that thing she said to her guardian when she needed 'a rest'? Obviously her guardian is also her personal sex toy
Jecht - I can't shake the feeling he's really Jack Sparrow. And Rikku I've barely met.
So to get to the end of this rant - Tidus, Kimahri and Wakka for me. I'll go with Wakka. Had Kimahri not had a dog face I would have gone for him.
