One problem is that DeepSilver has quite a history of releasing buggy games (i.e. Gothic 3, Dead Island, Risen), on the other hand, even those games were quite good in their own rights.
Not to open up another controversy but you shouldn't cite Gothic 3 here ... Deep Silver only handeled distribution outside the capabilites of JoWooD (who were the primary publisher on this) and it was JoWooD who enforced the unrealistic dead-lines Phirana Bites set themselves in the contracts for the project... leading to short cuts in development time and QA
Note: JoWood went backrupt sometime ago and will never ever ruin a franchise again (too late for Gothic and SpellForce though) - the remains of that company too were absorbed into Deep Silver
