Build this kind of game
Make an RPG With AI: One Village, One Quest, One Fight
Build one village, one quest and one fight that work together, then grow from there. Keep every number in one table and add saving early.
Find the pictures your game asks for that are missing from the published build
On your own computer every unit and building has its picture, and online half of them show as empty squares. Often the file exists but is spelled a little differently. Here is a check that compares what the game asks for with what you ship and says which problem each one is.
Save the game so that a crash in the middle never costs the whole city
If the game closes while it is writing the save, the file is cut off and the player loses hours of building. Here is a way to keep two copies, check each for damage when loading, take the newest good one, and never overwrite the only good copy.
Check your list of buildings and costs for typos before they break the game
When the AI edits your numbers, a misspelled resource or an upgrade that points at a building that does not exist turns into a game that quietly gives away things for free or crashes at the third level. Here is a check to run after every change of the list.
Cancel a unit in the build queue and give back exactly the right amount
Players cancel queued soldiers all the time. If the game gives back too much, they find a way to make coins out of nothing; too little and they feel robbed. Here is how to charge, reserve room for the unit, and refund so that the numbers always add up.
Keep your strategy game small enough to load on a phone and on a free host
Strategy games collect art and sound fast, and one forgotten giant picture can double the download. Here is a check that adds up what you ship by kind, compares it to a budget, and names the heaviest files so you know what to shrink first.
Make a building fit the map in any turn and still touch a road
A wide building that is turned sideways suddenly covers other tiles, hangs over the edge or ends up only touching a road at its corner. Here is how to check a placement properly and how to tell the player which rule they broke.
Build a control point that is captured slowly and freezes when contested
A flag or tower that changes hands needs care. Two armies standing on it should freeze it, a big crowd should not capture a hundred times faster, and the owner should not change the moment a single soldier steps on. Here is how the progress bar should move, tick by tick.
Stop a broken save file from wrecking your city builder on load
A city that loads half-empty, with buildings floating outside the map or a treasury showing nothing at all, usually comes from one bad value in the save. Here is a checker that reads a save before the game trusts it and tells you exactly which entry is wrong.
Give every teammate the credit they earned for a defeated enemy
Whoever lands the last hit gets all the glory and the reward, even if three others did the work, and teammates start to avoid helping. Counting only the final blow is simple and unfair in a team game. Here is a way to credit recent damage fairly, split the reward, and still honour the one who finished it.
Make hitting your own teammates hurt a little, never ruin the run
If teammates can hurt each other, careless shots turn into arguments, and if they cannot, explosions feel fake. A middle path needs a few exact rules for who takes how much, when it must not kill, and what to do about a player who keeps doing it. Here is a set that keeps both fun and tension.
Start a lobby countdown only when everyone present is truly ready
A match that starts while a friend is still joining, or counts down with someone who just clicked away, leaves one player behind and everybody annoyed. A ready check seems trivial, yet joins, leaves and changed minds during the countdown each break it. Here is what must restart it and what must not.
