Editors’ Notes

Rome wasn’t built in a day, thank goodness—where would the fun be in that? Build Away! doesn’t require your constant attention, but this captivating cartoon city might keep you coming back more often than you’d expect, as you check on your construction creations and rake in all that sweet, virtual cash. Adorable interactions, cool surprises, and a neverending stream of clinking coins make it an urban architect’s delight.

Poor game design


Nice animations and overall presentation, nice eye candy but some serious game design flaws.

So the goal for each stage is to collect population. Can you guess what's the most efficient way to do that? Taking down your buildings. I don't know who thinks this is a good idea but the best way to pass a stage is to take down your buildings and rebuild repeatedly.
To pass any stage:
1. Acquire reasonably amount of money (1aa) takes you 2 minutes
2. Upgrade the cheapest house to lvl 3
3. Change it to something else then back to the cheapest
4. Repeat step 2

There is literally no need to care about the profit gameplay at all. No need for cards, no need for any other buildings. Even when pretend to care about the profit why would anyone build anything that is second best? I only use one single building and opening any legendary doesn't affect me at all.

Could have been such a nice game but I bet the lead game designer dropped out of high school, that is if there is one.

If you want to fix it, makes population generate from money, this way we would actually care about profit. Make your building non-repeatable, this way getting new buildings feels rewarding and exciting. To solve the mid-game-little-progression problem, make carnival games etc a big boost so that player can get pass it

Its a time killer


Im giving this title 5 stars because it has a nice art style and does good for an idle game. There isn’t a lot to it so the game is more of a progression toy than anything. I find myself playing it a lot. Each building has its own prestige style system so you have to prestige each structure to generate population which in turn boosts income. Sometimes the fastest route to the most population is to prestige a building down to the trailer then immediately upgrade it to start building population. The game is what it is and does have addictive qualities. Numbers go up
