I don't consider it much of a classification issue... but the given is if you are a gamer, you must play games in general, usually of the electronic nature.
But, there's still some (albiet not very heated) argument over the subdivisions... "hardcore", the ones whom can beat certain games without looking. "Casual", those who play rarely and only for passing amusement. "Collectors" who just piss everyone off by hoarding rare games yet never using them.
By the subdivides, I'd be a casual collector with minor hardcore tendancies. I like rare ones, I -am- a general hoarder, but I play them all. But the numbers... I can't be a complete expert on my entire collection. Maybe if I had no job, no need to sleep and never had to ingest foodstuffs, but...
What I think is stupid is the rabid system loyalty that used to exist in the Genesis and SNES era. Owners usually -hated- each other. People were shunned for not playing whichever system was locally 'in'. It exists these days, but at a less vehiment level. I was a Nintendo fangirl 'in the day', but I was curious about the Genesis. I had a friend whom had one (we both had a mild fascination with X-Men, too) and I so wanted to visit his home and share some quality gaming, but alas, I was never allowed. The division was mainly -caused- by the cost involved. $60 apiece for new cartridges, the systems were... what... $100 or $150? I don't remember console price... but the Saturn was $200 when it debuted, albeit with the three game inclusion pack.
I'm ambivalent these days. If I love a game, the system is less important. Unless it's the Saturn. It's my pet system. Purchased four years + after its death, it still has suprising and interesting titles. Come on, Super Tempo was actually really, really good, albeit unheard of! Its predacessor, Tempo 32x wasn't a quarter as good... but they learned.
