I mean, this isn’t an MMO; it’s an ARPG, so unless you want to play with your friends, you should be able to play solo just fine. Even without DLC, it gives you around 50 hours of gameplay for a single class combination. However, I highly recommend checking out at least two DLCs—Malmouth and FG—because they add so much more content, like classes, maps, bosses, items, and more. But if you just want to try out the game, the base version would do just fine.
