I finally managed to play at UFO ET, without comparing UFO ET & UFO AI there is something that i would suggest to fix in our current version.
Having the possibility to rotate the camera everywhere is very nice, the isometric view is nice too, but both are not handy at all, I found them even annoying after a while because using the camera requires some accuracy & concentration - I think this harms the gameplay.
It would be much better to have an additional FIXED view like the old xcom or the new ET - I understand that I can still chose a view and stop rotating the camera, but what we need is an optimal angle where we could see any Phalanx & aliens without having to rotate the camera. Current isometric view would be ok if soldiers where not seen too much from above.
I know my english is not very clear, I hope you are able to understand my idea.
I think that would be a good improvement since player wont have to micromanage anymore the camera.
