I haven't been seen enough of it to be bothered so far, so my current stance is that we need more of (tasteful) asset reuse to ease game development. Creating games takes way too long and costs way too much. I seriously doubt whether we need every studio to recreate similar realistic-style assets for their games.
Maps are a trickier thing though. The chances are that it'll easily become annoying, but I love tasteful map reuse. Revisiting previously visited locations is something I've always enjoyed, but I can definitely see how it could become annoying.
