I'm currently engaged in one (for weeks) including the addition of new furniture and stuff, found so many things.

Tragically, though, my SSB Melee and Pikman cd cases were empty. I went on ebay and even for disc only they are not at all cheap :(

Also, I found out I had doubles of like 5 ps2 games, super Mario sunshine, a few xbox360 games, and for some reason had 5 dreamcast controllers and 5 gamecube controllers.

I've wasted a lot of money.

ah that feeling of confusion and doubt.. "wait.. Didn't i just saw that game..." strangest thing is that i did nothing with my extra copies of Armored Core 4, Star Wars Force unleashed 2 and some other games and just put them back in the box next to the other copy..

Please.. Like i had real life friends who came to the house.. 
Besides.. I was playing Gran Turismo most of that Summer till Metal Gear, Half Life and Ocarina of Time came out..

I agree. Spent a whole week with my cousing playing split screen co-op...on the same keyboard, trying to get through the whole game. Was brilliant.

Nice.

Hah I'm probably going to bring them in (and the extra GC/dc controller) to some retro store and see what I can trade for... Maybe it's enough to get that missing SSBM.

I cleaned my room completely a while ago, and you know what I found? ~1000 $ in cash

That was just so unbelievably epic.
