Amclass: My interest has been piqued here, it seems like the consensus is that I should just play the second one though. Or is it worth it to start with 1?
binteon: 1 is harder because of narrower view, you have to proceed cautiously, with some levels requiring multiple attempts (memorization of some traps). In 1, one place has a trampoline where you may need to use a slow motion cheat code otherwise it's almost impossible). With 2, you can breeze through the whole game. 1 is also longer. It's most helpful review says it's overpriced but given the amount of content (relative to other games of its era) I think it's worth it, especially on sale.
1 I believe was the first DOS side scrolling game to run at 60fps. Most impressively, it could even do it on my 386 33mhz with an ISA bus. The author of this game chose not to do parallax scrolling, while other PC games did so at the cost of performance trying to match 16 bit consoles which had hardware support for multi layer tiled graphics and sprites. 60fps vs 30fps was very apparent on a CRT monitor with 30fps having ghosting.
Well, I've seen Jazz Jackrabbit 1 longplays on YouTube and I can confirm, even if I haven't played Jazz Jackrabbit 1, it looks hard and has a timer which Jazz Jackrabbit 2 doesn't have, but there are also 4 difficulties, namely Easy, Medium, Hard and Turbo. These difficulties also exist in Jazz Jackrabbit 2 except for Turbo being in JJ2+. Jazz Jackrabbit 1 could basically run on anything, it dosen't matter what platform you're on, you could still run it on an Intel Mac with a virtual machine (I personally use Parallels Desktop) and a copy of the game. On Linux you could do the same thing, just use a virtual machine, and if you're on an ARM processor, just use QEMU, which can emulate x86 hardware, and it could even run on every version of WIndows ever. No matter if it's Windows 11 or Windows 95, on Windows 11 the GOG setup installs DOSBox because Windows 11 dosen't have a NTVDM (because Windows 11 only comes in 64-bit editions), and it isn't based on DOS. Now, if you would install Jazz Jackrabbit 1 on Windows 95, which is based on DOS, you would be able to run it with no problems at all. Jazz Jackrabbit 1, now keep in mind that this is 1994 we're talking about, and most people were probably still using DOS or Windows 3.1, and if Epic Megagames (nowadays Epic Games, the Fortnite idiots) had added 16-bit graphics, multi-layered stuff and parallax scrolling, "good" performance on 1994 computers would be thrown out the window and the average computer user in 1994 had 4MB of RAM, 120MB of HDD storage and a 486SX-25 or -33. Performance on a computer like that would've probably been chucked in the trash can if you had tried to run any game with 16-bit graphics, parallax scrolling and multi-layered stuff, let's just say your computer would've already exploded (in reality, you would've had super crappy performance). Now, you may be asking, why would I run PC games on a Mac. And the answer is, I don't. I have a secondary Windows XP PC which is where I run my old PC games from GOG because, using a virtual machine, on a 2016 MacBook Pro, with Windows XP, would make my CPU flaming hot, which then ends in overheating. So, I have to configure my fans to always be on max speed with iStat Menus, and also have to use a Cooler Master laptop cooler at full blast. If you read this to the end, I salute you, for having the most attention span I have seen in a long time.
