Alright so I really want to track down this old computer game I used to play. It was an RTS, and the main resource was milk. It wasn’t Polanie, and I remember playing it in the early 2000s. I remember the storyline consisted of some orince being cursed by a wizard with a big gross nose.

For the life of me I cannot find anything on the game, or any info about it. I figured I’d make an account and ask the users of gog since some of you who weren’t 7-9 at the time like me might know what I’m talking about.

Thanks!

My guess would be
Once upon a Knight / Knightshift

So have you found it yet?

Quote from metacritic: Set within a world of treachery, nobility and milk (yes, milk), Once Upon A Knight delivers powerful gameplay and forgoes conventions surrounding ordinary fantasy titles offering a milk-based economy, mother-in-laws, flying witches and secretive knights named Floyd. Right-o: it was "Polanie II":
Polanie II , also known as KnightShift and Once Upon a Knight, is a real-time strategy and role-playing video game hybrid developed by Reality Pump Studios and released by Topware Interactive for the PC Windows and OS X in 2003. The game is a follow-up to Polanie, published by USER in 1996. https://www.youtube.com/watch?v=JQNJo6kdOs8 (intro - shows big nosed wizard, cursing the knight/prince)

So, my guess is, Dreaganos gave the right solution, but the OP didn't mark it as such.

Looks like a spammer to me.
