Show HN: GeoChess – open-source geography strategy game

4•spider-hand•5d ago
The rules are really simple. Players take turns claiming a country that shares a land border with the current one. You lose if you have no valid moves left.

I'd appreciate any feedback.

This looks really nice. Something new to play with friends on game nights, will try this one out.
spider-hand•5d ago
Hi thanks for your comment. Hope you enjoy it!
gus_massa•5d ago
I expected the countries to be a painted when they are selected.
spider-hand•5d ago
Thanks for your feedback!

If they are visually selected on the map during the game, I thought it would be too easy.

Maybe I can add an option to let users see which countries have already been used on the map.

gus_massa•4d ago
I don't see any selection neither.

It may be nice to start in the same continent of the player. I know better the countries near here [Argentina]. North America is quite linear, so it may be boring to plat there.

spider-hand•4d ago
> I don't see any selection neither.

Yes it's intentional. I thought if players can see the selection during the game, it is not challenging.

> It may be nice to start in the same continent of the player.

I think letting a user select a continent is a good idea.

gus_massa•4d ago
It's too hard. I know enough geography to play only in a few parts of the map.

How good is the AI? We made a few mathematical games a few years ago and our problem was that the computer used perfect strategy. We had to add an easy mode. Perhaps your AI can have an easy model that does a shallow search to avoid stupid errors.

spider-hand•3d ago
Ok thanks for the feedback. I will add an option to show the used countries during the game.

> How good is the AI? We made a few mathematical games a few years ago and our problem was that the computer used perfect strategy. We had to add an easy mode. Perhaps your AI can have an easy model that does a shallow search to avoid stupid errors.

Yeah even though it says AI mode, it is just based on a simple algorithm, otherwise, players can never win. Just made a small difference between the difficulty.

Loaded it on a pixel phone, saw a list of countries with no context about what picking one meant, saw a map but didn't understand how to interact with it, and that was about it.

Like it! However Denmark and Sweden apparently aren't "connected"!

Which is fine of course, but would be nice if the rules made that clear!

I played about 8 rounds and I still don't understand the goal.
