I don't own any rare games
Either you don't know what a rare game is you're lying through your teeth about what's in your collection.
It says you own the following...
https://vgcollect.com/item/22501 (1941: Counter Attack)
https://vgcollect.com/item/10460 (Shining Force II)
https://vgcollect.com/item/9826 (Metal Slug AES)
Hell, let's expand on that and show your whole AES Collection...
https://vgcollect.com/oldgamerz/neogeousNot to mention you own dedicated arcade machines, conversions and CPS-1/II boards.
1941 on SuperGrafx was rare when I owned it 15-20 years ago and was fetching over $100 back then. Metal Slug 1 was always a couple of hundred to start and has only gone up since. You may not have paid "rare prices" but it's nonsense to say you don't own any rare games when any one of us can look up your collection with a few clicks.
I honestly never paid more than $30 for a used game in my collection, $40 is the highest I spend for a game. all my cartridges are loose but most of my disc based games do have the case and manual. I don't own anything rare or sought after in fact some of what in my collection is off a ROM cartridge I bought 500 games for about $56USD once. If anyone sells a game for a higher price they are probably going to sell it off ebay.
So the above listed games were bought new? Is the sky the limit on new games? If $40 is the highest you'll spend for game, I'd LOVE to meet the person who sold you those arcade machines/boards for so cheap and see if they have anything I can sucker them out of for pennies.
you can believe I'm troll all you want but I honestly don't have any rare games, that most people will buy
All that stuff listed above is quite desirable. I'm not saying you're a troll but I wouldn't be surprised if you lived under a bridge and had a thing for billy goats.
I do keep a collection because like you I'm a collector but I don't go for $100 plus single games that are so called rare. I would rather spend my $100USD plus on a console or a new PC. Some games are ridiculous and values go down over time sometimes.
Some people buy a video game expensive and it goes down in value, but like some have stated somethings go up in value, it's a gamble
Far be it from me to determine what a collector is. Some would look at my collection and say I'm more hoarder than collector and they'd probably be right depending on the context. Having perused your collection I've noticed is is largely FPS and sports games. Then there's the arcade machines and the standouts listed above that do fetch a nice amount on the market so again, it's erroneous on your part to say you own nothing rare/desirable.
