it would also be important to ask questions that couldn't be easily researched. for instance, i hardly know anything about the new fe game (the one on gba, not the upcoming gc one), but i know where to find lots of stuff about it. thus, it would be best if the quiz questions were analytical to an extent, requiring understanding (rather than trivial knowledge) of a game. for instance, i can ask you what were the 2nd fastest pokemon in rby (jolty, aero and m2), or who the sixth fastest falling character in ssb:m is (it's marth). i could ask you what the base stat total of arcanine and crobat are in gsc and the advanced generations (555 and 535 respectively), or what the fastest fire pokemon is (rapidash), or the 7 longest-ranged grabs in ssbm (sammy, link, ylink, marth, roy, yoshi and kirby, in that order). but this does not reflect mastery of either game - it just means that i've memorized the base stats of a number of pokemon and some of the character attributes in melee.
however, a quiz that demands, for instance, analysis of the competitive aspects of ssbm would be quite interesting for me.
