wow.. "45 employees" .. that IS interesteing O:)
The WP entry is almost, but not quite, worthless. It notes that they were involved with Sakura Taisen and then don't even mention the games under the Sega Saturn section below.
I've known RED's games for a long time, but nothing about THEM.
Did either of you actually go to their website?
If you click the "About RED" link, that opens a second page with general statistics on the company. On this page, there are now a few options on the left you can click on to see more in-depth details, including a timeline of the company's growth.
I'm not sure what more you want to know about them. Are you looking for information on their founder's mother's maiden name? Curious about their lead programmer's bowel movement regularity, perhaps?
Seriously, their site tells just about everything I could possibly want to know about them. The only thing missing, as has already been pointed out, is a complete list of all games they have had involvement in.
