Since I´m still puzzled, I´ll try and guess.........mmmh............"Final Fantasy: Chrystal Chronicles"

Maybe this will help your memory:

Her spiked armband has me thrown, though. I don't think she's from Darkstalkers or the King's Bounty girl whose image is occasionally requested on GOG:

Though you do collect blue crystals in the King's Bounty games.

I notice she does have a spiked anklet though.

My doggy is much cuter than Mr Fox :p

It´s like a mix between Mr. Fox and the Mad Hatter :P
So I would say "Alice: Madness Returns" but no succubus in there.

If anybody looking for a sum up of this riddle look into the attachment.
I still got nothing -.-'

EDIT: is this a pc game or console?

Number 4... looks like Morrigan .

Darkstalkers ?

It's a PC game

Now we just have to cross-reference it with a list of games with dogs(with a hat) and we've got a winner =]

I am going to guess Disgaea.

EDIT: Nevermind, I just saw the latest clue.

I still have no idea - probably I have never even seen this game. But I'm impressed by how fast cmdr_flashheart's drawing skills evolved. It's like she's Goku from Dragon Ball except with graphic arts instead of martial arts.

Keep improving like this and you'll surpass grimwerk in 4 weeks, Van Gogh in six. Overtaking DaVinci and Michelangelo in nine or ten weeks.

I have no idea what game this is, but that first picture is hilarious.
