Borderlands 2 has a lot of replay potential without getting boring. It never plays the same way twice. The weapon drops are very different each time through. Don’t forget the DLC. The rest of the games in the series are fun too, but BL2 seems to be where it peaked for me.

It also has a very high rewatch value. Each time through you notice something you missed the previous times.

I find myself rewatching occasionally it when I introduce someone new to the series.
