I imagine people like me will play Mass Effect 3‘s co-op long enough to see what it’s about and quickly lose interest, moving back into the quiet realm of offline play.
It all seems to come down to how much you enjoy the series’ brand of combat. I’ve never been bored by it, but I also can’t say it’s particularly engaging. Of course, that could all change with Mass Effect 3. This trailer is reassuring, though videos like these are never perfectly indicative of hands-on play.
