My weird 2 cents:
My Game Explorer is Excel (!!). I have this huuuuuuuuuge Excel sheet with tons of PC game titles... It includes Release Dates, Genres, some Review Scores, if I own them, if they are installed, if I finished them (and when), if they are available on GOG or Steam... It is "my personal metacritic, all in one file". So, when I am looking for the next thing to play, I filter all games I haven´t finished (about 80 of them right now), by year, genre or whatever I am in the mood for, and pick one.
(Big defect for you: no shiny little pictures) :)
Since it contains stuff I do NOT own, the spreadsheet works as a buyer´s guide as well. For example, I can filter everything GOG offers, sort it by Average Critic Score, then use my personal preference to pick something to buy. Lovely!
Now, for the disk organization part: I used to keep all my games in a second partition, carefully organized in different folders... I even had directories for series -- so there would be D:\Divinity\Div1, D:\Divinity\Div2, etc. With my new Windows 7 machine I finally said "SCREW ALL THAT DOS-THINKING!"... ;) :)
So now I let Windows put the games wherever it wants (unless it is REALLY absurd) -- and I Windows Search if I must (for mods and tweaks). Google Mail trained me to think like this -- STOP SORTING FOLDERS, JUST SEARCH THE DARN THING! It has been working very well, in part because I usually play only a few games at a time, which are pinned to the Start Menu until I am done with them... I spend less time fiddling with Windows, more time playing.
Cheers!
P.S.: Now, I will go back to finish Titan Quest now (up next, the first Fable). I am calling from 2006, what does 2011 look like? :) :)
