Value of Doom 2 for GBA and others

[playfortoday]

Hi everyone, I'm looking for the right value of gba's DOOM 2...i read everywhere it's difficult to find! It's an european release, it is complete with box and manuals. it's not sealed but never played.

I also have these two, if someone is so kind to "price" them :)

Comix zone complete with box and manuals (never used but not sealed). I think this is an europe only release...

Contra advance alien wars ex complete with box and manuals (never used but not sealed).

Thank you VERY much!

[Parodius Duh!]

$15-20 for doom 2 if its cart only. Couldnt find a complete value but its probably somewhere around $40

$30 for Comix Zone complete.

$30-40 for Contra complete.

FYI, Just because they are "New but never used" is not going to raise the value, youll still get what its worth to purchase a loose complete copy or loose cart. The only time "New but never used" really matters is if its a disc based game thats easily scratchable, thats when the cosmetic condition matters and can effect value (ps1 discs especially), not so much with cartridges (unless of course like the label is torn off, then I wouldnt even buy it, compared to say a nice label that doesnt even have an indent on it I might pay a couple bucks extra).

Thank you very much!
yeah i'm aware that if it's not sealed the value goes down :/
it was just to notify that the condition are like new (ex:the cartridge never came out of the little plastic bag).... the problem is that the store where i bought them unwraps every game from the cellophane :( ...MY GOD, WHY?
