Still fighting depression/burnout (retirement, here I come), and I exhausted my Baen backlog. So, I picked an old series, Sean Oswald's Welcome to the Multiverse. Systems are basically merged god pantheons, and competing for resources and fighters for said competition. Earth gets put in a competition with four other worlds - the first gets all the resources, the second and third become dungeon worlds with an expected 90% death rate, and the last two are used for mining resources, and anyone who can't leave in time dies. The MC gets recruited as a Forerunner, the five people who try to score points, because his uncle (who died during the competition) set up a succession to his closest blood relative.
MC gets showered by every loot, title and bonus imaginable. His CHA is so high, women wet their pants in his presence (yes, that's in the book). He grabs stuff from all sorts of other systems and becomes the usual one-in-a-million-years wonder. So obviously, everyone sends their daughters to seduce him.
Problem: he does have a girlfriend. And he's not tempted by harem stuff.
Overall, it's not a very complicated or original series, but it's very easy reading (some minor editing problems).
Rating: 6/10.
