As the title says.. all I can remember of it was the game was full 3D RPg and it was turn-based for the battles. One of the characters had an afro hair style, I'm pretty sure it was an indie game cos it took the mick out of loads of stuff, and you fought a weird messed up Pikachu in it, liek if it was zombified or something. Anyone know what game it could be? iv'e been looking around on google for hours now and STILL can't find it.

Since you've said it was 3D instead of 2D I have had to deduce out several games from Zeboyd Games such as On the Rain-Slick Precipice of Darkness episodes 3 + 4 & several others. Ditto also to 'Barkley, Shut Up and Jam: Gaiden', a freeware sequel to a Genesis/SNES game. Video example. Wait a minute, is this yet another freeware sequel still in the making since ending its funding campaign at the end of 2012!?!
So could it be either of the first two episodes of 'On The Rain-Slick Precipice of Darkness' licensed by Penny Arcade?

Oh wait! 'Pier Solar', first designed for the Genesis and then ported with a HD makeover to the modern computing & gaming systems? Have a look at that screenshot in the link back there. It features one character that seems to have the afro hair thing. But it's 2D...

Penny arcade on a precipice of darkness is NOT the one. Pier Solar is 2D AND you dont fight pikachu in it. whoever made that Barkley shut up and jam should be sued for copyright.. what EVER possessed that person to create such a game? It's NONE of those you mentioned.. I THINK this game was probably released about 5/7 years ago maybe.. ???? I also remember the title of the game being utterly pathetic.

Maybe it's Chantelise: A Tale of Two Sisters that was first released in Japan in 2006 and localized by Carpe Fulgur in 2011? I can't remember many Japanese made indie JRPGs on the PC before and after then. I have played it but gave up due to the awful camera and movement controls! Though it did have some big boss monsters to battle. Not sure if it'd have a souped up Pikachu enemy, although it does have a number of small bizarre creatures with funny shapes. Be sure to check the HG 101 link in that Wiki page above.

Or it could be Carpe Fulgur's another localization called Recettear?

LOL! Oh man. I'd completely forgotten about this title. And, yes, one of the in-game gang's characters do look like an aping of the Samurai Champloo anime guy! Hehe. Is it any good? This review from a trusted RPG 'fan-site', so it seems legit. But I think the battle scenes do look cool in a parody way.
