Hmm, I think my global comment would be that unlike standard Inform best practice, here you might not want to include all those synonyms and just have each action represented by the main verb – for a limited-parser game, it can get confusing if the game seems to accept anything other than the small list of actions the player is specifically told are accepted, and plus, it dilutes the theme to have alternatives available.
Relatedly, I probably wouldn’t have distinct verbs for take vs take from – that distinction can be hard to communicate to players who don’t know a lot about how Inform works (the difference between putting something on a supporter vs. inserting it into a container is also like this). I’d just use the same verb and have different grammar point to different actions if it’s important to keep them distinct on the back end.
As for the specific verbs to choose:
- GO - I like MARCH, but really, people are just going to type the directions.
- LOOK – is this LOOK or EXAMINE? You kind of need both, and you really want both able to be abbreviated to one letter. ASSESS could work for LOOK (“a” by itself isn’t already used for anything, right?); EXAMINE is tougher, I’m honestly not coming up with anything better than Treasure’s (R)EGARD.
- GET - SEIZE works for me, but PLUNDER as a more aggressive approach can be fun too.
- DROP - maybe RELINQUISH?
- GIVE - hmm, none of these seem sufficiently Conan-y to me, maybe PROFFER? PRESENT?
- TALK - CONVERSE with? BANDY WORDS with?
*ATTACK - I think SMITE has you covered. - USE - EMPLOY? EXPLOIT? I tend to shy away from USE, though.
