Hi all,
After playing through the shard game, I went straight to sandbox on a large standard map, Impossible difficulty. It was... not impossible.
I don't want to whine about it too much, and I don't want to just drone on about how you should "Improve AI!", because you're already doing that.
I do have some other suggestions, mostly in the form of the inclusion of new game options:
1: Option to disable diplomacy
Add an option to disable diplomacy between you and the AIs on hardest difficulty, where you would be in a permanent state of war with them all the time (This option could give you a lot of points when you finish the game). This wouldn't just make the game more difficult, but also rid you of the AI constantly pestering for you for an alliance, or trading that damn 67 gold for 45 mana every damn turn.
Alternatively, you could add a "diplomacy difficulty level" instead of a downright disabling option. This would have the AI be more adverse to being allied with you, and more likely to ally with other AI against you.
Additionally, when playing multiplayer coop, add the option of creating AI teams. Maybe have all allied against the human team, or teams of 3 AI vs 3 AI vs Human team, something like that. (I haven't actually been able to play MP yet, so I don't really know how possible this is to implement.)
2: Monster Spawns
The AI is having a lot more trouble with this than I am. Maybe add an option that gives the AI a "soft start" somehow, making them able to grow in strength instead of being totally subdued by monsters, which seems to be the case of some of the AI players in the "impossible" game I just played.
3: Turning off water
Simple. The AI has problems with water, so add an option to disable ALL water in your sandbox map.
4: Give AI advantages
In most games, such as Civ, the AI gets great benefits on harder difficulties (more income, less unhappiness, etc.), so why not do the same in this game?
The most obvious here would to give the AI a higher
City Limit than you. This could be added as an option box, again giving you more game points if you win on harder settings.
Additionally, the AI could be given all sorts of other advantages, such as gold/food/mana income, or unit strength. This kind of "direct/obvious AI cheating" might not be as fun to play against as some of the other things, but really... ANYthing to make the game more challenging.
I know very little about game design, so I don't know how hard these things would be to implement, but... in all my ignorant glory, it sounds kind of simple.
The best thing about these suggestions is that they are optional, so if someone doesn't like playing with them, they don't have to turn them on.
So... how about it?
