Subverse: Almost What We Wanted

A critical analysis of Subverse by Studio FOW - how a promising NSFW space opera fell short of expectations and what CSE learns from its mistakes.

My Mission and why I'm building CSE

Gaming's gone soft, sanitized corporate crap values profits over passion, avoids NSFW risk and originality.
But as a solo-dev, I'm free to make a dream game.
I believe Tolkien proved that
Passion × Singular Vision, applied over decades beats the revolving door of soulless corporate hell.

My mission is RillMent, that is:
The thRILL of raw adult experiences +
fulfillMENT of intellectual depth.

Join the rebellion against mediocrity!

Give it a try, a new universe awaits!
