This thread got me to register and reply. Personally. I'd prefer to have the UFO interior be seamless with the exterior map. Redesign the UFOs if you need to. Hell, go back to squared off boxes like X-Com had if you need to. I don't have any problem with multi-part missions, as a rule, but I can't see any legitimate excuse as to why you can't have the interior of a UFO be on the same map as the exterior. Cutting it up like that just breaks the immersion and ruins one of the best parts of any UFO mission, the entry. If you're not allowed to choose when and where you enter a UFO(within your abilities), then what's the point? X-Com even had extra holes poked in the UFO if it were particularly badly damaged, giving you natural extra entry points... without special interior maps. If the devs can't at the very least meet the same feature set of a game that's nearly 20 years old, when trying to do a remake of that game, then there's something wrong. Now, I just seriously sat down to play the alpha a few days ago, I gave the kickstarter demo a try and loved it, that's why I invested in the full game just recently. And while I do love a lot of it, and love the feeling it brings back, there are still many cases where I find myself thinking, "Well, X-Com did this better..." It's slowly getting to the point where I might as well just go back and play the old one.
I'm just now getting to missions where I have more than 1 or 2 aliens to kill on a map, so I admit, my experience is still lacking compared to many of you on these forums. But just judging from the small and normal scout crashes. They generally feel right. Maps are a bit repetitive at times(Even worse than X-Com, but hopefully that's being worked on). I wouldn't mind seeing a few more holes in the hull of the UFO, but this is generally how an assault on a small, lightly crewed UFO should feel. I'll continue playing and continue waiting and while the current state of the game, at least what I've seen, gives me much hope, these forums put some fear into me that this is heading in a direction I won't like.
I also realize, this being my first post, and being critical may come off badly, I don't mean to be that way. I want to be supportive, I wouldn't have paid for the game if I didn't, I love anyone who has this kind of respect for the early X-Com games, even if their vision isn't the same as my own. I'm just putting my own opinion out there, one more voice among the masses that may or may not get listened to.
Edit: Missed the size part of the opening post, but if scale is a problem for the larger ships... then perhaps you're thinking a little too big...
