Student
So, I played two games today with trade port and (the first version of) student.
Take everything what I say here with the necessary 'first impression' caveat. So no need to make any definitive calls.
The first student gave:
Spring: +$1
Summer: +1 Action
Fall: +1 buy
Winter: +1 Card
The new student:
Spring: +1 Action
Summer: +1 Card
Fall: +1 buy
Winter: +$1
We played with the first version and it felt really weak. So weak, I would even say that even the new student will feel pretty weak. You have to play him every season, so you need to buy multiple, but it doesn't get good until really late. We haven't tested the second student yet - which is obviously better - but even there you *have* to buy multiple, to make sure you play them once every season.
I *think* that I would give student +1 action, +$1 from the get go. So that ultimately, you end up with +2 actions, +1 card, +$1, +1 buy.
That looks strong, but you really have to *work* the card to get there. Otherwise it never gets better than a bazaar/worker village; and you don't get it from the get go. In order for it to be attractive, there needs some sort of bonus for it.
I think that the order I would use, if you do that:
Spring: +1 Action (2 actions and a coin)
Summer: +1 Buy (2 actions, a coin and a buy)
Fall: +$1 (2 actions, $2 coins and a buy)
Winter: (2 actions, $2 coins, a buy and a card)
If you do this, you could also bring the price to $4, maybe. That's a strong card, but remember: it's not that you can use it a lot.
I like the mechanic, but the way it's done with the first student, felt very weak. But again: maybe the second student is already sufficiently better.
Addendum: the designers (Asper & Cookielord) agreed that the card was slow, but that it's not necessary to buy multiple, as long as you can play one a season. They also recommend the second version (with which I haven't played yet).
