Haven’t played recently, but this one came to mind’
I missed the original, but Scorched 3D was a big hit at my high school.
OpenTTD
Beneath A Steel Sky (though I kinda prefer the grungier aesthetic of the Amiga floppy version)
Available free on ScummVM!
Has an excellent plot and wry sense of humour. Fun game.
Do flash games count? Motherload is great.
It’s been a few years, but Armagetron Advanced was the best. Felt like you were riding the lightbikes from Tron.
If we’re sticking strictly to free, I’m not sure Doom mods work if you only have the free version installed. Either way, people basically never stopped making wads since the game came out, and I try various ones out from time to time.
There are tons of them, so if you’re interested you can see what won the annual Cacowards throughout the years and start there.
“Einstein puzzle” by Flowix games, copyright 2004-2005
I play it from time to time, to see if I can still complete it in under 4 minutes and my brain isn’t slowing down too much with age.
Technically, Dwarf fortress is the oldest game I still play, but I only got fully into it thanks to the non-free Steam version.
I often revisit Soldat
One of my absolute favorites is a quirky strategy game named Lord Monarch. I found it on the Nihon Falcom website way back in the mid 90s when I was first starting to use the internet: Lord Monarch
It’s super tiny in modern terms, but I remember waiting a good 20-30 minutes for it to download from a 33.6Kbps modem.
Another huge one for me was a game I actually got a full version of from a Gravis gamepad promo CD named Seek and Destroy. It’s a top down shooter where you can be either a helicopter or a tank: Seek and Destroy
The last one that comes to mind is a giant robot fighting game that also came on that same Gravis CD named One Must Fall: One Must Fall 2097
Lost Vikings
For the longest time I thought Minecraft was free because I only ever pirated it. Lol
PlanetSide 2 is the free-to-play I keep going back to
Heck, I still pirate it even though I bought it. (I didn’t want the hassle of migrating my account after the Microsoft buyout.) PollyMC ftw!
Clonk! It’s a 2D mining/strategy/base-building hybrid that was apparently more popular in Germany than other places. I actually paid to play it way back in '05, but it has since become freeware. It’s got a particle sim (similar to Noita, but not as extensive) that plays into the scenarios well.
Warzone-2100
I’ve played Simutrans on and off ever since the mid 2010’s. I’m not any good at it, and usually play it without regard to a lot of its mechanics (especially managing finances), but I’ve spent countless of hours just connecting communities and cities with over-engineered roads, rail systems, ferries, and airplanes.
Wolfenstein Enemy Territory, or the modernized remake, ET Legacy
Neat! I had a ton of hours in ET, played competitively for a while, and made some silly mods for my clan.
