Gameboy Advance recommendations

[CyberRazorCut]

I was being a bit sneaky by not listing what I have as I'm after more unprompted recommendations on some of the stranger titles I've bought but not yet played :). 

Ok, the games I have are as follows:

Sonic Advance 1-3, Donkey Kong Country 1-3, Denki Blocks, Metal Slug, Go! Go! Beckham!, Namco Museum, Yoshi's Island, Columns Crown, F-Zero Maximum Velocity, Finding Nemo (bought for my nephew's birthday but cynically retained after I played it), Chu Chu Rocket, Sonic Pinball Party, Mario Golf, Mario Tennis, Kuru Kuru Kururin, Astro Boy, Gunstar Heroes, Lady Sia, Wade Hixton's Counter Punch, Hajime No Ippo, Sega Arcade Gallery, Tony Hawks 2,  Iridion 2, Spyro Eternal Night, Klonoa, Klonoa 2, Rayman 3, Mario Advance 2, Mario Advance 3, Mario Advance 4,Wario Ware, Super Monkey Ball Jr, Game & Watch Gallery 4, Ninja Cop, Final Fight One, Zelda a Link to the Past, Zelda Minish Cap, Mario Kart. 

Looking into (i.e bidding on): TMNT, Metroid Fusion, FF Tactics, Tactics Ogre, Wario land 4, Mario Vs Donkey Kong, Gradius Advance, Kirby Nightmare in Dreamland, Splinter Cell, Kirby & the Amazing Mirror, Mario Bros NES Classic.

Games I'm looking patiently waiting to appear on Ebay unboxed:

capcom mix, guardian heroes, mega man zero 1&2, Doom 1&2, ultimate card games, Pinball of the Dead, moto racer advance, fifa 2004, drill dozer, Spiderman Mysterio something or other, baseball advance, racing gear advance, guru logi puzzle, sabre wulf, ct special fotces 2, double dragon, river city ransom, space invaders EX, Metroid Zero Mission, the Fire Emblems, FFVI.

So as you can see, I've spent a fair bit of time on this particular subject, but already a few games have popped up in this thread I'm not aware of.  What's Road Trip: Shifting Gears, or Riveria?  What's that Contra game like on GBA?

Thanks guys.  Keep 'em coming.
