Well, I decided that starting over at Easy would be a better way to spend my time. Some non-combat but dangerous stuff was easier. ALL combat was easier, although that first Gorn still took far more damage than any Gorn after him, so his mini-boss status is confirmed. Space Battle didn't seem easier, although I still haven't watched somebody else do it to know how to get the second Achievement.
I did stop playing, though. I can't STAND the crap going on when you try to get to McCoy. One problem is that when you start that section over, you are in cover and you have to quickly shoot the infected dude who runs into the room. Then the other dude. Then take both down. This has degenerated from Hard into a random stealth-failure that can't be explained. I mean, the stealth commendation is revoked yet I did exactly what was expected. If not these two, then the next two. Stealth still in play per the screen. One outside the room, one inside. Stunned and down, no problem. Get upstairs and start crawling and the screen shows that stealth failed again. Huh? If somebody else saw me, who was it and why didn't they attack me? Rather than worry, I'm returning the game.
I'm not sure how much XP is was generated by printing the resource locations and picking them up as I went, versus XP you get as you go. I added the tricorder stuff I would be using later, and had over 3,000 left, so since it's optional to keep all the stuff you added in a previous game when you start a new one, MAYBE you can make multiple short runthroughs to have your equipment in better shape earlier. If all the XP came from finding things, at least you can be well equipped by finding them all. Some were not easy to find, even if you were told where they are. I'd suggest YouTube.
To all those doing well, I salute you...
