So I'm 34, putting me in between Bob and the crew age-wise, I believe, and I was totally enraptured with Star Tropics, the commercials, the two issue spread over Nintendo Power, etc.
I enjoyed the game when it came out, immensely. The pig butt in the first village, how the chief looked like Mario, etc. I did think the first chapter was too small, and the second chapter as well (the dolphin was cool, and even if it was linear, the secret passages in the map screen did instill the thrill of finding a secret), but than chapter 3 gets BIG, and hard. The special weapon system and stars were, and still are, a very odd system, and the tile based movement and puzzles felt off even back then.
The worst is when you spam a yoyo (main) attack while trying to walk towards an enemy, sliding a tiny fraction. The frantic, snapped jumping also feels off.
Chapter 4, if I remember, was all map, all in a whale, no combat. Left an impression on me and feels like an "indy game" moment now.
The infamous parrot in chapter 5 was the last of the smaller chapters, again, if I remember correctly, but really embraced the goonies feel, at least for me. Then the game opens up with a series of islands and space ships for the rest of the game. It's never as non-linear as, say, Zelda 1, but it does afford some exploration. The difficulty spikes at the end are pretty egregious, I remember a powerup called Vitamin X (?) that would heal you, and then start hurting you after. Drugs, don't do them.
My grandest memory was beating the game, and then having Mikey swim a bit in the map screen and drown, with the death music playing. I wanted to take a photo of the ending for Nintendo Power and kept wondering what I had done wrong to drown, and then finally it's revealed the dolphins from the 2nd chapter have rescued you. Good moment.
Playing it years later on VC just heightened the fact that the core gameplay is janky, but I still liked a lot of the design. Those ostriches with skull heads are freaky, and of course dipping the letter in the water is a great gimmick.
As for Star tropics 2, it's waaaaaay more linear than the first one, and the time travel motif doesn't have the same appeal as exploring the tropics in your submarine. Also, the hidden pits in the map screen are no fun. Didn't like it at all.
As much of a Startropics fan as I am, there was a kid in my school who wrote 50 page fan fiction sequels to the game in spiral bound notebooks. I thought it was pretty weird.
