You would go to other people's houses and play games there.
I played a lot like that too. A friend of mine would always buy the wrestling games for Playstation and I'd but the ones for N64 and that way we'd get to play all of them.
10-15? We had maybe half a dozen or so,
Back then, at least in my area, every neighbourhood would have a gas station or a drug store with maybe around 100-150 movies and 20-30 games to rent on a couple racks off in a corner. One of those spots sounds more like what he's describing in his post.
Then you'd have some bigger stores closer to the centre of town, your Blockbusters and whatnot, and they'd have thousands of different movies with 50-100 copies of popular new releases and maybe 200-250 unique games to rent at any time, with 15-20 copies of really popular new releases. Blockbuster would generally have just about every title that would have been available for you to buy locally at department stores and stuff, plus they used to have exclusives you couldn't buy, but could only rent at Blockbuster like Indiana Jones Infernal Machine or Clayfighter Sculptor's Cut for N64. You used to get really good deals on used games and movies at Blockbuster when they were selling off their old stock too.
If you were really lucky, there'd be something like a Microplay close by and they'd have just about every obscure title available for rent and even some imports. They also used to rent PC games. I remember renting Starcraft four or five times before I got my own copy.
but nobody jumped around between them just to look for something if they were out of what you wanted. Unless they were out of virtually everything then you'd just get something else rather than going to another rental store.
If you were looking for a specific game, you wouldn't go into the store with your hands on your dick like a mongoloid. You'd call ahead to see if they had it. If they didn't, you'd call another place. If you couldn't find it anywhere, you could reserve it and they'd put a copy to one side for you when it came back in. Of course they often came back late.
My point was never to argue all this worked perfectly, just that there were 100% ways to try games before you bought them if you really wanted to. I've also no doubt that some people who were not old enough to drive themselves to a video store during peak video rental era and just had to go to whatever store their parents took them to have a different view of video rental stores.
Talking about gaming in the past as if video rental stores didn't exist has become a really weird tell in online discussions about gaming. Especially when people drop the old "games actually costed more in the 90s" in discussions about the cost of Switch 2 games as if people didn't rent most of their games in the 90s. I owned about ten SNES games by the late 1990s, but I had actually played at least 100.
Also, demo discs didn't have every game and some were only available through limited means, like how are you gonna get it from a magazine if that month's magazine is no longer available? I feel like I remember Pizza Hut giving them out sometimes too.
They were everywhere in the PSX era. Magazines, cereal boxes, preorder bonuses, restaurants, cases of cola, etc. You'd trade them with friends and stuff too. There are games I never would have tried at the time if I hadn't gotten free demo discs like Unjammer Lammy and Threads of Fate. I kind of miss getting the little disc with 4-5 curated demos for games I never would have played otherwise.
