Another MMO - this one's based off of the Final Fantasy universe. Similar to most Western MMOs, I suppose - but with stuff like Chocobos as mounts.

PES 2011
I'm sure everyone knows what PES is, bit weird to see a beta for a sports title... but eh, I figured I'd list it regardless. Hit the link to sign up, if interested.

Despite that, developers have managed to turn it around for them and make their game worth playing. Here are some games that had a rough start but were pretty great."
Sea of Thieves... I'm not disagreeing that the game has improved in terms of content. But I feel that the most significant change between now and its release is actually the public perception. Nowadays, most people are aware that the game is a multiplayer PvP-focused experience first and foremost, and not "Black Flag made by Rare". Consequently, people dismissing the whole experience because the single-player aspect is lacking or the story is plain are much less common.
The long-rumored Gears of War collection is looking ripe for a 2024 release, and a possible Xbox showcase reveal alongside Gears 6 could not be more perfect.
Even though the games are easily available on Game Pass, a remaster of the original titles would be cool. I believe only the first got that treatment back in the Xbox One's days. As for Gears 6, honestly, it's not that Gears 4 and 5 are bad, far from it. But at this point, I feel just like Halo, it could really take its time, 4 years is already a lot but I feel a couple more would do well for this series.
Another Crab's Treasure spends much of its runtime commenting on the dangers of capitalism, and the character of Firth is the perfect example of that.
grrrr.
thank you :)
