Alright I've done some playtesting and I gotta hand it to Cole. The more games I've played the more it seems completely unnecessary to add house rules to this game to ease up the difficulty, it really shows that he playtested the hell out of this game before releasing it.
The only areas that actually seem to need minor tweaks
in my experience are bug meat acquisition, animals, and game length.
For animals I was thinking that having two professions that focus on crops (watering can/hoe) is kinda overkill, and there's possibly room for either replacing the hoe or just directly adding a 5th profession focused on animal husbandry.
Also speaking of game length, I have playtest the two year campaign.
The main changes to the 2 year campaign were:
Year 1: 4 goals as normal + 6 bundles
Year 2: 4 year 1 goals turned back faceup to be completed again in addition to the 4 unused goals, for 8 total goals + 6 new bundles.
Also several goals in year 2 are increased in difficulty.
All Joja tiles must be gone by the end of year 2.
As well as several other changes that I'm not going to go into full detail on in this post, you can find the full campaign files
here. (note: I wrote it for 3-4 player games only)
The intention was that year one would play as normal but with the epic items gained in year one and other things like marriage being used to their fullest to beat the extra hard 2nd year.
It played perfectly actually, if not a bit too easy (completely won by the last day of fall, and had so much surplus gold that Joja tiles would be immediately removed if they showed up winter)
It was brutally long as well, too long. So much that I am abandoning the idea of a 2 year game. I only work on what is fun for me and to me 2 years is too damn long.
I am now going to focus on coming up with a way to balance adding more season cards and a 5th grandpa goal to the standard 1 year game.
1 year is too short but 2 is too long, I will try and find an in-between that feels good.
I would also like to report that the Wizard Tower idea worked out incredibly well. Felt fantastic to use and didn't feel like it screwed up any of the difficulty at all.
