It’s more or less a double edged sword, you can get new players or retain the ones you have. I say it like that because if Gearbox tried to do both I assure you they will break something else in the process.
If we get new players the old ones who are still here ideally are going to still be here so retention isn’t THAT big of an issue. New players are going to see all the cool looking characters then realize the characters are end game tier which means they have to play stupid amounts of games before they can really have fun. That’s a terrible thing to throw on people who you expect to BUY your game as well.
Then you can go F2P and there lies the bigger problem, if the game keeps the same state it is currently in and goes F2P you will get an influx of players…for a month if that. Then we would go back to the same problem we are currently in. Evolve is a game that tanked as a buy to play game and with that it went F2P it did well F2P for a time until the same crap that made the buy to play players leave made the F2P people leave also.
