Before I learnt it's a prequel to Portal 2 (a presequel, if you will), I had a shiver from recalling what insane bullshit Portal: Prelude mod was. It was genuinely great in using, abusing portal mechanics, but even back then in my youth I couldn't suffer through it. Shit has it's own steep learning curve.
