I assume you can totally do that with Cy_Borg as well. There’s just rule 0 that states “corps and cops are always the bad guys”, doesn’t mean you can’t side with them or seek them out for protection.

Imo, the intended use (of all the Borg games) is for you to have maximum freedom and flexibility in how you want to run it.

You can play pre-written adventures (note, there’s (at least, depending on the version you got) one already included, Lucky Flight Takedown. Apart from that, you might have Reaper Repo if you got the KS package, otherwise you may freely download it from their site: https://cy-borg.io/dlc/), come up with your own stuff, or use the (excellent!) mission generator. I think the generator is intended to be used prior to running the mission, it would definitely make it much easier to do so. You could, however try and use it during the game, for a challenge (i.e. I think it’s way harder to run zero prep in this system, it’s not like Brindlewood Bay). Or, just use particular tables, e.g. if you need a short side quest to send the party on or throw them a curveball with table 09 COMPLICATION or Location Features.

You can make your missions as complicated/complex or easy as well as railroady or streamlined, or narrative or battle-heavy/crunchy as you like (well, not that crunchy compared to later D&D, TBE etc., for starters, you might have noticed the Borg games don’t feature skills or proficiencies etc., just abilities).

The “usual” game for Cy_Borg (and other Cyberpunk RPGs, I think) is a heist or heist-like or a courier mission, but you can just as easily use a different adventure template.

What about One-shots with pre-generated character, would customizing PC backstory and give them individual goals (Like you would do when playing Vampire) would go against the OSR/Borg philosophy where you want to keep it quick and simple.

Yeah, surely you can do so! Cy_Borg is not as deadly as Mörk Borg or Pirate Borg, in particular because healing tech/drugs/services are more freely available (albeit expensive, usually). You might end up with a PC with only 1 HP, but again, of course (especially with pregens), you’re free to fudge them to have 5 or 6 hp or whatever. It’s your game, do whatever is fun to you (and your players)!

Final question, the game offers a way to create a kind of apocalypse/great-reset. Is it a way to keep the campaign length capped ? Do you even use that option ?

I haven’t yet, but they’re also in every Borg game. The idea is that the world is both pre- and postapocalyptic and that the upcoming apocalypse is very much inevitable and on the horizon at all times. Yeah, one use is that it may keep your campaign length capped (you can’t level that much anyways and the Borg games are pretty deadly as is), but also for setting the scene, ambience. It’s mainly narrative, but you can add actual ingame consequences (some of those e.g. bring an active civil war or corp war into the game, possibly making it harder for the players to go after their quest undisturbed, but at the same time, it might help them get/carry weapons more easily or something like that. It might lead to the destruction of a particular district or the emergence of mutants/aliens/whatever (I don’t have it memorised)).
