Bumbling through it again as had a disastrous 1st play-through. Even on normal difficulty it can be pretty savage (then again I'm terrible at strategy games) so save-scumming is the way forwards - a look at the story missions is pretty vital as they are much harder than their rating suggests - and then you can go off & build a lance that works for them.
Turn-based: No problem, I played the tabletop. I was crap-ish at that too! This game is a pretty good interpretation of the rules. I'm cool with that but if you came in from a Mechwarrior computer game background you may be confused.
Load times: Yeah, I have it installed on an M.2 drive/16GB RAM/Mobile i5 so no idea what it's doing. May investigate network traffic because calling home is about the only thing that could explain it.
Glitches: I had one that required a mission reset (escort mission, cleared out enemies but APCs wouldn't load into dropship) but been OK otherwise.
Lore: Played tabletop + RPG + related games, read most of the source books available at the time (early 90s) and a lot of the novels. Mainly used 3048/3050 rules & scenarios, though. This game is around that time period and I've been given some newtech - double heat sinks - but I'm yet to see updated Mech designs. I.... was a Battletech lore nerd at the time.
New DLC: Not played it. No immediate plans to, either.
Grind: I'm kind of enjoying it as I haven't table-topped in decades, so am having fun swapping Mechs & loadouts around. But I do agree that if you just want to blast through the campaign you may be in for an unpleasant time.
Yeah. You have to think of this as a remake of the original FASA tabletop game! It does a very good job of this. Remembering all of the rules was a pain in the backside, plus the endless arguments over whether a Mech was in cover/higher or lower/etc with the people you're playing against. [hehe]
