Escape from Tarkov: $150. 18000h. $0.00833333333 per hour.

bought CS:GO a decade ago on sale for like £3 and I still play it (ignore the cost of the cosmetics i bought)

Even before it went F2P, Rocket League. 10,000+ hours, and counting.

Elden Ring for one, because my buddy liked it so much he bought it for me. Not sure if it counts though because I ended up passing it on and bought a copy for my brother so we could all play together.

Otherwise Splitgate, free basic ass arena shooter that is the only thing that has scratched the itch that quake 3 started me on when I was a child.

Most: Fallout 4, I have over 7000 hours in it. Bought it pre-launch with season pass.

Least: I have no idea, probably several games I bought and never played.

I think for me it's either Minecraft or Monster Hunter World. I don't know how many hours I've spent on Minecraft, but I assume it's close to 1000 as I used to play it with friends daily when I was younger. Me and a couple of friends also got Monster Hunter World at the start of the covid lockdown and we ended up playing it more or less daily. I have 380h on it, but I think I've enjoyed it more than mc. Both of them costed between 20 and 30 €.

For the worst, if a series of games count then it's the Trails of Cold Steel series. After playing Azure I was excited for it, so I think I've even payed full price for the first or two. I ended up hating everything about them and convinced myself to play through, hoping the would get better, but ended up dropping the entire series a quarter of the way through CS3 when I saw there was no attempt at improving them.

No Man's Sky. Seems like getting good RNG is the difficulty of the game.

I don't have the original disc, but absolutely Roller Coaster Tycoon 3 Platinum Edition. Most bang for my buck, enough back in the day I found a copy online and had an amazing time playing it again. I LOVE it more than the first 2 games purely for the ability to ride the coaster first person rather than through 3rd person following the track.

As for least bang for my buck, absolutely a Hot Wheels Stunt Track that I picked up thinking it would be like Beat That. Didn't even make it past the first level without hating it. Was just a single stunt jump and then the level ends from what I can recall.

Check your local library, can rent console games for free!

Tormentor❌ Punisher

Bought it on chrono(gg) for $1 and have something like 500 hours in it. Made it to number 2 on the global HardMode leaderboard.

Both one of the most difficult and infuriating games I've ever played, but one of the most skill-based and almost infinitely playable... Crazy considering it's a 2d top down arena based shooter.

Gotta be either Anno 1800 or one of the Monster Hunters.

RE9 is probably on the lower end for me. Was excited and paid full price and didn't even get more than an hour into a second run before I got bored. The game is good but a depressing amount of it is basically on rails, kind of like the Beneviento house in RE8.

For 70 fucking bucks, it needs to ship with a mercenaries mode or seriously different NG+ mode. Insanity stops being interesting as soon as you get the blood collector and start making OP backstab injectors again and ironically showcases how actually rather unobservant most enemies are.

Compare that to games like Abiotic Factor, which are half the price (and I paid less than that because I got it during its 0.9 early access patch) and I've clocked hundreds of hours in or games like WoW or FFXIV which have clocked several thousand hours each.

WoW. Never paid a dime and played thousands of hours.

Otherwise probably Captain of Industry.

I used to play WoW back in the day, and I would pay a monthly subscription of 13 euros per month, for three years straight, which is a total of around 470 euros, but I would play 8-14 hours a day almost everyday (for around two years), so in the end it was a good overall value-for-money (although a complete waste of time). Minecraft is also in the top 3, with a licence of 25 euros (while it was still owned by Mojang) and countless hours (easily over 1.000). But the biggest value for money was is Skyrim on Steam: I got it for 1 euro in a sale, around 330 hours spent (playing vanilla on my Steam Deck). I had to quit it cause I could see it going to the thousands of hours easily.

Biggest regret so far is Rimworld: paid full price (30 euros), played less than two hours. I always say I'll make it worth its price someday, but my backlog is already in the hundreds, so I don't see it happening any time soon.

Mount and Blade Warband, CKII, and EUIV are all up there extremely highly but I guess Warband due to less dlc.

Least is tougher. Probably a couple of NES stinkers from way back would be in the running. Though lord knows I have games in my steam library I've yet to play. Hard to say.
