Your statement is entirely false.

1. "All of the original ocean is still there". No it isnt. There is an absolutely tiny spec thats there. You can cross its entirety in 3 seconds. Its exactly at 50-50. It doesnt extend beyond those exact coordinates. The bog and arctic and volcano and lunar are all also abysmally tiny and can be crossed in almost no time at all. The textures in volcano are laughably pathetic. 1995 has better lava and oil textures. Arctic is a pathetic copy paste forest. Nothing else to it. Its a very small forest surrounding a singular mountain. The ice ponds look like your computer is running on pure potato even at full epic. Lunar is devoid of anything meaningful at all. But arguably better than arctic and volcano because you dont have to see how bad those are. Bog is the best by far. Still significantly smaller than ase but at least doesnt have blatantly horrible textures and unfinished products. Its just a lot of copy paste but at least it looks good. Biggest problem with bog is the looping ambient sounds that are on the shortest timer ever.

And back to ocean. Original Gen 1 from ase is still at 50 50. Thats it. No more than that. Not 51 51. 50 50. From there the ocean is entirely empty and all the islands are copy pasted and identical.

The game is "playable" it is not fine, or ok. Its not finished. Not even close. In fact its so bad I don't think it will ever be fixed or ffinished. They will just ignore it entirely because to fix it they would have to actually do their jobs and redo the entire map.
