Top 10 Worst GBA Games 

Poor ET can't seem to get a good game.

I would add both Sonic the Hedgehog Genesis and The Ripping Friends

oh god i remember when my dad bought flight of the falcon.. i realized that i should make a wish list before he goes buying awful games..

The original Defender is one of the best early 80s arcade games, right up there with Robotron, Asteroids and Centipede.

I thought gba van hellsing was good because a friend told me, he was either coping or didn't play anything good before it

I almost bought Flight Of The Falcon once, thinking how bad can a Star Wars space flight combat game be? Good thing my prescriptions ended costing more than I thought they would that day. I'm the only working class person ever to benefit from stupid medicine prices.

The list lacks Kao the kangaroo GBA by Titus

Mortal Kombat Advance should've made this list

i remember that shitty ET game, i played this as a kid, im pretty sure the game was in english and not my language, so i had no idea what i was doing, probably the worst game i have ever played, unless you had an instruction manual i guess, it was impossible to play. problem was it was not my game, i just borrowed it from another kid and they most likely threw that away xD

Bionicle on gba is my contender to the worst game tbh. Nonsense game with extremely floaty controls.

They all have one thing in common licensed games

I don't see why you feel the need to bring up review scores, as if those matter.
