Like many, I would always game with family and friends growing up and getting into my teens. Would play the occasional "mainstream" games at the time, be it COD, FIFA,Halo, etc with mates but we would spend just as much time playing Smash Bros Melee/Brawl, Mario Party 1-4, Bomberman, Street Fighter, Metal Slug and many more strong multiplayer titles well after their original releases. Single player games like Donkey Kong Country, Zelda, Banjo-Kazooie, Lost Vikings were others I would replay once every year or so.
Having already held a keen interest in retro already, following this I started seriously collecting and actively buying/selling/trading around 2006, got my first job in retail when I was about 15 so had more disposable income at the time than usual There was a local Cash Converters on the way to/from work where I would stop before/after work. That was the beginning and where those foundations were built and then it just evolved from there. Would keep an eye out for other second hand/op shop/thrift stores when out and about as well. Not long after discovered various collector forums, eBay, Gumtree and more places to find stuff and from about 2010 onwards more digital communities like Facebook gaming groups, the old NA,Retro MMGN, etc to converse, buy, sell and trade with other like minded people.
Very lucky to have built the bulk of my collection(SNES, N64, GC, GB/C/A and a bit of PS1/PS2) before e-commerce truly taking off and with that increased interest/prices in the retro scene. I've now pivoted over the past few years and am now focusing on certain Game Boy/ Color/Advance games/consoles, expanding my Donkey Kong collection(variants, merch, promo, employee items and anything in between) and any Nintendo promo/advertising items, of which the latter isn't really appreciated as much here in Australia compared to the rest of the world! That can keep prices down! All up it's been an enjoyable ride and a great outlet!
