Got Borderlands 4 from Gamefly and decided to throw it in a couple nights ago….just to check it out. Hadn’t really planned on getting into it seriously, but man, it completely sucked me in. It's absolutely great. The open-world map is solid, and there’s loot evvvvvveryyyyywhere. There is also a ton of weapon variants to collect and they all feel really good to shoot. The graphics, even with the cartoony cel-shaded look, are crisp and really well done.
I've only uncovered a small section so far, but the map appears huge, with lots of areas to explore and plenty of things to do. The only minor downside I’ve noticed is that enemies respawn pretty quickly. I cleared out a giant building during a mission, and by the time I was leaving and heading out the way I came, they were back. It doesn’t ruin the game (you can always just roll through past them) but it does take away a bit of that “I just conquered this place” satisfaction.
Otherwise, it’s great so far. I’m having a blast and seriously contemplating just buying it.
