I've been wondering, what's the common technique for

Scene context, sentence context, and consideration of the target age group. If it's a game for kids, it's easy enough to assume they're not going to be throwing around a lot of difficult or uncommon words.

Common sense, generally.

Honestly, kana only is a poor choice for a first game, those titles only existed because of screen and memory limitations. You're much better off with slightly later children's titles that have furigana. Games aren't a great choice for learning, especially early on. When you reach an intermediate level with a few VNs under your belt, you'll find stuff like this completely trivial.

I've never found a retro game that uses furigana, not even in the 32bit generation.

I'm not being a jerk, btw, just honestly curious.

I was implying a move to non-retro consoles, really. You could probably find some PC titles that got there earlier.

Kanji aren't hard, anyway. You can learn the vast majority in a few months, and they help a lot with memorisation.

For MM you can just play the PC98 versions instead of the GG ones.

I disagree. VNs overwhelm you and have too little interaction to make sure you understood things. In RPGs you get time to think about information and expect you to act according to them.
Much of the SFC, PCE-CD or PS1 libraries is suited for starters.
