✦ AI summary

Classic Marathon is praised by players as a well-designed, atmospheric shooter that runs smoothly on older hardware and remains engaging decades later, with accessible mod support and a compelling story that particularly resonates with fans of the series. Common complaints include awkward controls that require adjustment and notably loud sound design, though these issues don't significantly diminish the overall experience for most players.

There are not many games I can play on my current hardware, but I'm glad this is one of them. Great atmosphere and fun gameplay.

So far so good, runs at high resolutions and framerates without any instability, installing plugins (mods) is a breeze.

A downright excellent game, an absolute hallmark of its time that holds up extremely well to this day. This makes my heart bleed that we'll likely never get a proper remake or sequel to the marathon series.

I have no idea what crack Bungie was on when they made this. 'Nuff said.
