There've been some interesting developer services over the years that have been listed on Sumea but have now disappeared. They were good ideas but perhaps some of them were established well before their time.
Anyway, I thought I would put them in a forum post as some sort of record.
You can split your in-house workload by out-sourcing to LASTGUN STUDIOS. Based in Sydney, Australia, Lastgun Studios operates to service all facets of the computer game industry.
Madcap Motion Capture Studios provide motion capture services for Games, TV and Film. This means they provide super realistic human (or animal;) movement for 3D animators to incorporate into CGI for film, tv or games. This is done by a process of infrared cameras and reflective markers in their gymnasium sized studio. Advantages over keyframing include speed and efficiency of delivery, quality of motion and significant cost savings.
The focus of extremetesting is to provide Quality Assurance and Quality Control services for the world game development industry. Extreme Testing assists developers and publishers deliver top class games to the market by reducing the risk during the development.
