I too have been playing sims since the first game. I was introduced to the sims when my cousin had the game, and I was intrigued by decorating houses. My brother then asked for the first sims game for Christmas that year. I think I shared custody of all of the Sims 1 games with my brother, but by the Sims 2 the games were mine, all mine.
I think I (we) owned all the EPs for Sims 1, and I know I owned all EPs & SPs for Sims 2, plus a tiny bit of store stuff. But I haven't been as into collecting with Sims 3, so I don't have all the stuff packs. Although I do have way more store content this time around, so that probably more than makes up for it. :-P
Currently, I have all EPs and only three SPs. At the moment the icons on my profile are accurate *except* not showing that I own Monte Vista. I also keep a list of store items I own in "my blog" on my page.
I'll put my sims email up here as needed. I don't like to leave it up too long, as I don't check it too often.
