For whatever reason, Mario Kart Double Dash made a stronger impression on me than Kart DS (which as i said in my post, might be due to snaking making Kart DS so frustrating, whereas none of my local multiplayer folks engaged in that horrid practice), so it gets further up the list
Double Dash is also the first Mario Kart where i focused on winning on all difficulties. Gloriously frustrating, as this was the game that introduced the Blue Shell that's specifically targeted on the first-place racer
Monster Hunter: pissing me off since 2010.
