MBO: first time I broke a hundred in multiplayer (epicenter )
MBO: On all angles a blue gem spawned on the central tower. I had a MM, and a full blast. I mashed my jump, powerup, and blast buttons randomly, and ended up landing on the blue gem (skill not luck )
Zelda TP: killing the final boss first try. (seriously, they needed to dial up that entire game's difficulty A LOT. No boss took me more than two tries, and usually the first I would just do something stupid to die. I rarely if ever died from normal enemies, although I fell off quite a few times)
Mario kart Wii: Unlocking ALL of the 2nd level ghosts was fun, and general multiplayer is fun
SSBB: make a custom map that is shaped like this:
(The # represents normal structural things of your choosing. The \/ represents falling blocks)
###\/\/\/###
.....#.......#
.....#.......#
.....#.......#
.....#####
Put it on coin battle and get everyone inside the pit. Once the falling blocks respawn things get fun...
Rokkitball: no specifics, just certain games can be really really fun. (or could be, now that IA is down it doesnt really work )
MBG: finally beating tightropes' gold time
MBP: beating morph was pretty satisfying. (before all the glitches were fixed ) Same w/ TTotTSS, Mastering the Marble, and Space Station, although they all took so long that any sense of achievement was negated by realizing I just spent over an hour beating a single level once
Galcon Fusion: turtling tons of ships onto a single planet, letting the other players fight over my now empty planets. When they wipe eachother out I just clean up the pieces, taking out all of their planets that are now greatly depleted of ships.
