In this post, I’d like to focus on a gameplay element from my mobile game Play The Field and see how it helps improve the game’s overall balance and sense of fairness.
In traditional Real Time Strategy games (like Blizzard’s Starcraft series), each unit type can only be created at a specific building, and there is a time delay between the time the user decides to start building a unit and when it is finished. The opponent typically doesn’t know what unit is being built, but in some games like Starcraft 2 there is an indication that something is being built.
In Play The Field, in other to create new opportunities for tactics and avoid the extra work of maintaining buildings, units can be played anywhere on the map, given there is sufficient funds. The only exception is a few boards which have one or more red region(s), at which units cannot be placed.
In order to balance out for this extra freedom in unit placement, I made each unit take time to ‘warp-in’. During that time there is a visual indication that the unit is coming in and the enemy player can begin attacking the unit even before it is fully warped in. While a unit is being warped in it cannot attack or movie.
By adding this game element, the player has to have a good idea about the maximum attack distance of each unit and put more consideration into placement, which adds depth to the game. Placing haphazardly can lead to wasted funds and possibly even loosing the stage.
As with most gameplay elements, ideas only go so far – you have to test them. After playing a bunch of stages with this element enabled, I felt confident that it improved the game’s challenge in a fair way. It also helps to balance units that do spread damage to several opponents at once, since they cannot immediately appear in the middle of a enemy crowd and do damage before they are taken down.
