For someone who doesnt really follow Sega as a company but has a fondness for all things Relic... Is this a good thing? If so, why?
Sega doesn't have any walled garden of their own and are happy to steamwork everything, which works fine for many people. CoH 2 is already a steamworks game, so we wouldn't see any delay/problem with Relic being forced to change it for Origin or whatever.
Sega has done a great job supporting Creative Assembly, which has grown a lot under their umbrella doing what they are good at. Same with Football Manager. Actually their western arm is mostly focused on strategy games, with some car game in between.
Sega already has a deal with Games Workshop for Warhammer Fantasy, so it would be reasonable they could reach an agreement for Relic to keep working on 40.000 games.
The big thing is, is that given CA and SE has operated as usual and made the games we were expecting from them, Sega is probably the best candidate to make sure Relic keeps doing what they do without big changes.
