The exclusives in general have a bigger focus on quality, because it is more about getting people into the system.Same. I don't get why people really want their console to have exclusives.
I don't find enough time to play to invest into both consoles, so the more cross-platform AAA game releases, the better, for me.
Other games may have to reduce their scope and attention to detail because they have a lesser budget and their focus is largely about making money from that games sales.
Now if the games would be just as good without being exclusives, then exclusivity would be terrible and every consumer should be against it, but unfortunately they are a big part of differentiating between the systems.
