Hi All, I think that the Skyline Engine is terrific for building great levels, but the AI leaves a lot to be desired, especially when you try your FPS Level, those bots seem to dance before they see the Player, and the game play is antique.
I guess you would have checked out other engines, I like Game Guru, the LUA for there NPC's is a couple of pages long, and though not perfect, the game play is presentable, RPG Code would also be a great addition to the game play.
I realise that engineering a complicated piece of software like Skyline takes a large amount of time, and only so much can be achieved over time. I think that AI is a very important factor in the success of any Game Maker. I always look at the AI to see if I can make a game with the software, as I am not very good at coding.
Keep up the good work.
