MartiusR: Time flies like crazy.
Really entertaining game - one of those where creator didn't try to re-invent the wheel, but just put some known (and liked) elements together to make them as much enjoyable as possible - and did it very well.
It's a shame though, that while basic content is great to play, game doesn't have some content which would allow it to be alive and noticeable for years (map editor, multiplayer etc). After finishing it, at this point you can only re-play single levels or go again with higher difficulty.
It doesn't make the existing content less valuable (because it's great), but in current state Project Warlock doesn't have potential to, let's say, live in "long-term", like games which have active modding/level editing/multiplayer community, such as Fallout: New Vegas, Red Alert 2, Serious Sam, Duke Nukem 3D, Doom 2, Original War etc.
In my opinion - it's a real shame (can you imagine that after 2-3 years from this point this gem could be generally "forgotten"?), but I totally understand that being "one-person" company is not making easier changing this state.
The current climate of economic stagnation and competitiveness, and the general "uberization" of economy, forces creators to stop supporting their "brain children" if it doesn't bring coins; only big companies can do that, because they usually amass active users and generate revenue that way.
And, let's be honest here for a moment, Project Warlock was niche from the start, even if it was an awesome blast from the past. It never had a chance to attract any serious audience and it never had a chance to generate a stable income for the creator, because it has almost nothing to offer in the multiplayer department and that's where games get "monies" from nowadays. That being told, I enjoyed the game immensely, and the same can be said by many other players, judging from all Internet feedback.
