Looks like Obsidian invested in departments where they was struggling, Combat design & Cinematic design, animations etc...
In addition to those departments, they've also focused heavily on audio department since the purchase. But then again, if they are working on 4 different games at the same time, they need the manpower.
Hopefully someone forces Feargus to play Gears Tactics. Gears of War series itself is very consoly shooter with shit controls, but this spin-off series of the IP is solid. Pretty graphics, gore and cinematics with turn-based combat. Now if only Feargus would allow Josh or someone else to finally create a turn based combat game in Pillars universe (or some other IP).
Hell, they could even get help with tweaking UE from Coalition since they've already done the work.
