Space Colony is one of my all time favourite games. I bought the original - loved it and played it every year until they bought out Space Colony HD. I then continued to play it each year at Christmas and now Firefly Studios have released a new enhanced version for Steam.
"This remastered version of Space Colony features a brand new campaign, Steam Workshop support, achievements, trading cards and Steam Cloud for saved games.
Space Colony: Steam Edition is the definitive version of the sci-fi base builder for fans of the original, the builder genre and the Stronghold series, with which it shares DNA in both gameplay and an irreverent sense of humour."
