2003 - Koei - Koei
Crimson Sea is a Sci-fi inspired Third Person Shooter/Hack and Slash game by Koei. Immediately you can see similarities between this and Koei's Dynasty warriors series.
These similarities are only cosmetic though, as it plays more like Phantasy Star Online which is why I really loved this game in the end,
Honestly though, I have to admit this game hasn't aged well. The level designs and details feel grey & outdated and the controls are janky and take a while to get used to. This can add to the difficulty curve as the game is always switching back & forth from challenging to a breeze.
I did really enjoy this though and it was way better than I was expecting. There is also a sequel released on the PS2 which I'm going to have to track down one day.
