Might as well add one last game, myself. Haven't 100%ed it yet (and I don't know if I will), but I have rolled credits on it:
Tamarin.
To be blunt, this is a spiritual successor to Jet Force Gemini, one of my favorite N64 games, made by former Rare devs (including David Wise on the music) so however bad it may be I needed to try it myself. I took interest in this game after it made an appearance on Rerez's Just Bad Games series:
http://youtu.be/DtG8QNC5DiQThis game feels like 2 badly mismatched games forced together: something akin to a Banjo game and Jet Force Gemini. You spend half the game running around fairly generic open areas collecting Fireflies and completing challenges in order to power doors that take you to other areas. Aside from some absolutely infuriating coin-collecting challenges, these sections are generic but not too bad. The most annoying thing is if you die, you lose any collectibles obtained since your last checkpoint. This makes the later areas absolutely infuriating since there's some pinpoint platforming required over instant-death pits.
Then there's the other half of the game, where Tamarin gets handed an arsenal of guns and you run through a series of corridors shooting ant soldiers ripped right out of JFG. In these sections, you lose all your 3D platform movement abilities, which gets really annoying when the game hides collectibles behind obstacle sections that you can't use jumping dives or crouch jumps to clear.
And because it seems every spiritual successor to a Rare game is determined to not learn one major lesson from their predecessors, let's talk about Birds. Remember how much everyone loved the Tribals system in JFG, where shooting sections would contain lots of little furry hostages you had to save before the Ants killed them, forcing you to leave the area altogether and reload it all? Yeah, the Birds are Tribals, and they work the exact same way, but with the added bonus of also occasionally picking up and flying across the room to new lethal perches. and yes, the ant soldiers absolutely will gun them down if you don't kill them quickly, and you DO have to leave the entire area and reload it if you fail (or die, which resets back to your last checkpoint). Unlike JFG, you don't have to save ALL of them, but every 3 you save can be planeted in a birdhouse in the platforming areas for a Firefly and you need 40 out of 60 Fireflies to clear the game so yeah...you need most of them.
And yes, if you don't reach a checkpoint before you die, you lose any birds you've saved since your last one, which is all sorts of fun when the later areas are full of ants sporting shields and hand grenades.
I actually had a decent time with the platforming sections, but the shooting sections just got incredibly monotonous towards the end, despite there only being 3 of them, and the end of the game has you backtracking through all 3 of them in 1 sequence so that's just wonderful. Nintendo's playtesting is sorely missed here, as the shooting sections become utter mazes where it's hard to tell where to go to progress, and several times I ran into the end of the area before I was ready. And while Wise's music is pleasant enough, it doesn't even come close to the quality of the worst track in the JFG soundtrack.
