I don't know why they thought they needed Mobile Suits locked behind grinding/paywalls in order to fund this game. I'd imagine just getting people to want to buy more plastic models would be enough (it worked on me).
A very good port of a very good game. Worthwhile to check out if you happen to like both Metroid Prime and Doom/Duke and ever wondered "hey what if these two fused together".
I would have thought that by 1995 people have gotten a bit tired of NES-tier troll level designs with leaps of faith and all, but apparently it sold well enough to warrant sequels. I mean, thank god it got sequels, because they're generally all around way better than this one.
My spoiler free thoughts: Toby's still doin good. Characters are as endearing as ever, OST's good, plenty of unique puzzles and gimmicks and battles, and still leaving us with a story that has plenty to talk and speculate about. Bless this dude for giving us another chapter for free.
