It seems if you take the psychic elective, you will be trained in telekinesis and telepathy. This brings up an interesting possibility. Will telepathy-driven choices be included in the game? Can I cheat on exams by reading the mind of a smarter student? Can I know exactly the right thing to say to a person by reading their mind? Can I know where to find pokemon, and which ones are available, by doing a mind-sweep of an area? Can I use telekinesis to force that abra to stay still long enough to catch it?
If Red becomes proficient in his latent psychic abilities, it seems like all of these things should be possible. However, that would mean that taking the psychic elective makes the game horribly unbalanced. I'm sure Red would be a good person and not cheat, and not invasive-ly read minds, but using psychic powers for search and catching pokemon seems like abilities that if a trainer has, they would use.
Maybe all of the electives could have a secondary effect. Say, taking grass makes it easier to win gardening related contests that the gardening club hosts. Maybe fighting increases your stamina, and allows you to do 1 extra thing a day. What does everyone think the secondary abilities could be?
Here are my suggestions:
Normal - Lucky - You get more pokeyen after battles
Flying - Eagle Eye - Perception +5
Poison - Walking Pokecenter - You've been poisoned so much, you've gotten really good at curing it. Able to craft antidotes and other curative items in spare time.
Ground - Toph - Able to detect pokemon when not expecting it (when pokemon are underground, when there's one hanging around the dorms, etc)
Rock - Tough - Do not suffer penalties from pulling an all-nighter
Bug - Scientist - Your studious nature makes it more likely to pass exams. One incorrect choice for questions on exams is removed
Ghost - Calm Mind - With all the experience you have with tricky ghost moves, you can't be confused overwhelmed, or flustered. When given a choice, one "bad" choice will not appear
Steel - Full Metal - +5 Dedication
Water - Beautiful - +5 appeal
Grass - Green Thumb - +1 To all gardening related tasks (including flower arrangements)
Electric - Amped! - +5 expression
Psychic - Telepathy - When searching for pokemon, be given a short list of the pokemon that can be encountered, and pick one to encounter
Ice - Let It Go - The cold doesn't bother you anyway. Can participate in one extra outdoor activity in winter
Fire - Some Like It Hot - Can participate in one extra outdoor activity in Summer
Fighting - Stamina - 1 extra action per day
Dragon - Intense - Training gives +x experience
Dark - Bad Egg - Join Team Rocket
Fairy - Friendly - +x chance to catch pokemon. Or, +x additional pokemon happiness (if happiness is a mechanic in this game) per day
