Star Trek Online. I love the Star Trek franchise. I've spent so much time and money on it. It's got some old ass engine that the current team can barely maintain, it's super buggy, and there isn't enough actual content. They keep players in a cycle of perpetual events to keep FOMO up and the events are usually the same for each time of year, with different rewards.

It's F2P but all the desirable items are paywalled and many of those are behind gamble boxes. A single cheap ship that's decent runs $20 USD from their store. But one can realistically easily pay hundreds for a single ship with gambling. They sell ship bundles for hundreds of dollars as well.

Graphics are ridiculously dated. End game is a selection of instances that get repetitive, playing the game is intentionally grindy to encourage spending real money (you can buyout virtually anything you can grind out). Or running a specific instance over and over to clock your DPS and try to make a leader board only visible on a 3rd party application.

The community isn't particularly toxic but there's very little player engagement, chat zones are usually maybe 2 different places in the game and if the conversations aren't game related they are almost always political arguments/discussions. PVP is almost nonexistent due to limited maps for it and a lack of people queuing because they would be instantly murdered by money whales who minmax DPS.

The UI can be really confusing and there's a lame tutorial at the start that teaches you very little about the game. You will be doing endless internet searches for what should be intuitive and basic. There's probably more to removed about I'm forgetting right now.
