So I went ahead and bought this game over the weekend because I liked the original on the Amiga but never had the patience to do much in that game. I've definitely got a lot more patience these days and really need it for the Walrus pathfinding AI too. I've played the campaign in total for around 4 or 5 hours and I swear half of that time was spent hand-holding the Walrus units into going very short distances along paths with only 1 or 2 waypoints. To get anything done efficiently, I literally have to pilot each Walrus separately and get them to the position I want them to be in, then edge my way forward across the maps. I fail to see how this could have been deemed "acceptable" by any QA team prior to release.
I feel as though I have bought a game that is still in Beta because it is in no way polished or playable within reason. I've played many, many, many games in the last 30 or so years and this is the worst pathfinding I have witnessed in a simulator game to date... there have been other games with poor pathfinding but not so bad that you have to hand-hold every single unit every single time you want to move them. This issue should be the number one priority to being fixed in terms of gameplay fixes.
Some official word would go a long way to putting the concerns we have to rest...
