Man, I dunno what years I had anything but as a kid I had:
LEGOS (I think since day one I had LEGOS, y'know, the big fat ones for toddlers and then as a kid I got into the city playsets and the space ones were my favorite)
He-Man ( I seriously at one point had every damn He-Man toy, the vehicles, the castles, all of it. Then my brother was born and the demise of my He-Man's was abroad. I seriously told my mom when I handed her my Skeletor with a chewed on head "This baby needs to go. NOW.")
TMNT (me and my brother had plenty of these, mainly he did but what was his was mine but not vice versa, had the sewer lair and the van, loved the van,)
GI Joes (same as the TMNT, he manily had the figures and I'd get tanks and vehicles and we just shared)
ThunderCATS (had mainly the regular first ones, nothing much because I never really saw them much around here)
TransFormers (had a few, had to have Starscream because he's my fav outta all of them; will be getting some of the Classics line come this November)
SuperPowers (only had a few)
Marvel figures (those early crappy ones that really really really sucked but were so cool at the time because everything else was lame, I'm talking like the Punisher that had a trenchcoat made outta like trashbag plastic and Thor had no cape)
X-Men (Now these, damn, we went nuts on these. Me and my brother had litearrly all of them up until the X-Men 2099 figures came out after those we only got some here and there but all the others we had. The first series i had that horrid Wolverine bike and that Cyclops Danger Room thing and some other crap they put out. We had the crappy Sentinel from that line also. Loved the Deadpool figs from that crappy line)
Wrestling figures (had the crappy WWF ones with action features, atleast 20-30 of the damn things, then the next ones with bone crunching action and some WCW ones after those that eventually lead into what MLs became and what the TNA figures are now and now I get the WWE Classics)
Then.....I got a little older and I stopped playing with my brother much because i wanted to hit parties up and then there were girls and I just switched my interests away. I started doing model cars alot, I guess outta my habits building with LEGOS. I did buy wrestling figures here and there because me and him wrestled and stuff and we would atleast watch it together unlike when we were little and watched lots of cartoons and s*** and had the toys. I didn't buy any modern type stuff until the first X-Men movie was coming. I had been away from comics and all that for a long while, then I started hearing about. Then I got some of those movie figures. Then awhile later the MLs. Then the DCDs. Then Street Fighters. Then this and that and now, I just got way too much stuff.
And yeah, it sucks that my toys from being a kid were given away but atleast they went to kids who were poor and never would have a chancve at havingf those toys because they cost too much in Mexico. I remember my last trip (last year) I saw some Mattel Batman figures at this one store for $15 apiece. As much as i would like to have maybe a handful of my He-Man figs and TMNT figs back, atleast I know the were appreciated.
