I have been working in the videogames industry for almost 14 years now and have had the privilege of working with so many talented people. However, the size of team required to make a typical retail game now runs at over a hundred staff. Needless to say the more people you have working on a project the smaller the contribution an individual makes.
With a large team of creative people there are always a lot of suggestions made for every area of the game, often conflicting, and so the designers need to keep a tight rein otherwise the game will lose direction. And to see your ideas pushed aside and the game you will be working on for the next 18 months move in a different direction is frustrating.
I think the rise in the number of indie developers is partly fuelled by these frustrations. Games developers want to make games, not be given a list of models to build. Smaller projects allow that.
The Shoot ‘Em Up Kit is proving to be popular with games developers for their own projects as it allows designers, artists and musicians to work on areas which interest them using the same tools they use at work. Games developers, in my experience, are bursting with ideas and to give these creative people an outlet can only be a good thing.
