Game Trailers suck. They are not very good at selling you the game. I think this largely comes from the fact that they are trying to sell something in one medium (Video Game) by using another (Video). It's like trying to get people to go to see a movie by giving them a few lines of text about it.
I have not made a new trailer for the game in a while and my desire to do so is still quite minimal. I am sure I will make another eventually but I am not sure when it will be.
Because the best way to to get a feel for what the game is like is to play the game; I have decided to create a demo version of Engineer Alpha. It should be coming out within a week's time of this posting.
I have gone with a timed demo as I feel that is the best way for someone to get a feel for the game without feeling like they are playing some sort of chopped down and incomplete version. The Demo will have the full game contained in it but you will be limited in how much you can play within a single save file. Any save that reaches the limit of 7 in game days (2.8 hours) will be forced to exit to the main menu. The demo version is also not allowed to open saves that have a game length of longer than 7 in game days. This gives the great advantage that you can play the demo then pick up the same save in the full game.
