I don't play EECH at all. I never could get into it, even modded, it just didn't feel right. And with limited time nowadays, I just have to play what I want when I can. Although a lot of work has been done to improve EECH (and much respect to those involved), it still lacks the feel of sims such as LB2 and when I last played the modded version it still lacked fundamental improvements that should have been done from the start.
If you want an immersive battlefield experience, try the 'Chicken-Run' custom mission for LB2 from my website. It has air and ground elements all heading towards the main, massive target area. I also did edits of that mission to make it easier, and a night conversion to make the original even harder!
