Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

FTL: Faster Than Light would run on a computer that old, yeah? Probably bring that and a couple animes to watch while I play it.

Oh shit, if it's XP then I'd be good just playing pinball for the full 12 hours

probably some snes roms, an emulator, and some ebooks

Elder scrolls morrowind. 12 hours should'nt be a Problem.

Open X-COM. Or well, maybe the regular X-COM, that should run just fine regularly.

Some books as epubs or whatever format is convenient, and a reader. Would have to research which one works on Windows 2000 or ME. Or was it XP already?

There should be an external hard drive full of portable game installs in some drawer that fits the time period.

Should easily kill a week.

warcraft 3, sid's pirates, civ 3 or 4. portable of vlc for some classic 90's anime.

Surprised no one mentioned GTA series

12 hour morrowind marathon begin. and a few seasons of TV series I like.

Install the gta 3d games need for speed most wanted 05 and music from 80s to the 90s

Silent Hunter III

Sink some tonnage.

I'd copy my Doom and Quake folders, hoping the modern sourceports still work on them. Well, PrBoom+ and ZDoom should both work. Then all my emulators up to the 32-bit era, some music and the seasons of Kamen Rider and Ultraman that I'm currently watching.Honestly I could just bring my actual external hard drive or my HP laptop from 2013 that I installed Linux on. It's what I got on those.

Morrowind, RCT2, Total Annihilation with all my mods and Deadlock 2 as well if I have time.

12 hours? Lol probably just some stuff to code on and screw around in. I'll probably take a nap in there somewhere to kill time

I'd probably bring Warcraft III, Half Life 2, and potentially Deus Ex if the PC was extra shitty.

I would only need a copy of Gothic 1

Mid 2ks? Baldur's gate, in whatever version was usable

Diablo 2 with a mod: Project Diablo 2.

I'd download an offline copy of the wiki, too. And a build guide; 12 hours isn't enough time to come up with a build and play the game!

Max Payne 1 and 2, F.E.A.R, Far Cry, MAME with a couple of arcade roms like Galaga, Tetris, Pang, Puzzle Bobble, Metal Slug.

And if I get bored with those there is always Microsoft solitair, mine sweeper and mayong to fall asleep on the keyboard.

Civilization 4, Dungeon Keeper, Black & White just to name a few. See you next year. :p

Angband or umoria

Zsnes and a few roms

Some retro computer emulators(Atari 8-bit, C64) and my dev environment for them - when you target old stuff you can customize the whole dev tooling setup with very little compromise, especially if you go the route of assembly/Basic/Forth and then pile on higher level build steps. I'd have to be careful around the potential problem of "whoops there's a 64-bit binary in there and I'm on a 32-bit OS".

Basically if I were back in college it'd be that all the time, and then VLC and some anime or movies in 480p. No sense in keeping up with those darn 2000's games.

I'd love to chance to play a bunch of nostalgic titles - just off the top of my head I'd play DOOM, Uplink, Darwinia, Morrowind, and my trashy favourite from that era Themepark world. There are definitely more if I had time to think about it.

12h is barely enough for 1.5 out of 33 of Ascendance of a Bookworm volumes. I would probably rererereread volume 1 and 18

0. Newest Linux distro
1. G4 and G5 MLP episodes

A complete collection of QI episodes, and I'd be able to watch a fraction of them 😊
