This is a complete run of the Sim Ant Full Game. The black ants must have colonies in all 49 house tiles, and the red ants must be completely eliminated.

Game objectives

  • Emulator used: BizHawk 2.8 (Windows 64bit), BSNESv115+ core
  • Objective: Finish the Full Game as quickly as possible.

Comments

My Full Game run has two basic phases. In the first phase, which takes about 16 minutes, I try to get a population of 100 ants, including 20 winged ants, so that they can start spreading to the adjacent tiles. RNG determines a lot of factors in success here, such as locations of food drops, deaths due to the human and his lawnmower, etc.
The second phase is nearly all RNG manipulation, either by moving the yellow ant randomly or waiting a certain number of frames before selecting a new tile to move to on the house screen. RNG affects which tiles the winged ants spread to, and when they spread there. Obviously, it's best to spread to as many adjacent tiles as possible, as soon as possible.
When moving to a new tile, the total red and black populations are mostly determined by RAM values, but they can vary by a few ants due to RNG. The breakdown by caste is all RNG-based, with heavy weight given to worker and soldier ant counts. RNG manipulation ensures that the tiles selected will have at least 100 ants, including 20 winged ants, immediately triggering their flights to adjacent tiles.
During fights between the yellow ant and red ants, I rapidly press A and B (alternating 2 frames A / 1 frame B), to boost the chances of winning. A random value is selected at the start of the fight, and then compared to a second random value at the end of the fight to determine the winner. The first value must be greater than the second for the yellow ant to win. Every one of the A/B button presses increments the first value, and the fights usually last long enough to increment it well past the second value. When the second value is too large for this to work, I buy more time for button presses by briefly pausing the game mid-fight.

  • For the YouTube video, I wrote a Lua script to add an OSD to make it easier to follow my progress. It doesn't affect the game state in any way.
  • This run could be improved with better RNG manipulation to get faster migrations. I got the current results with lots of time consuming trial-and-error, but if someone could automate the process, it would be easier to search for better patterns.

slamo: Claiming for judging.
slamo: Great work for your first submission! It's awesome that you put in the work on the OSD to see what's going on throughout the whole map, and it helped me visualize what was going on. The route overall looks fine to me.
This game supports the SNES Mouse, and it would probably be a little faster to use it for some parts. I don't think its a dealbreaker, especially considering the amount of waiting and bottlenecks in the run. Any future attempts to improve the run should look into it further.
I think it makes sense to keep the branch name as "Full Game" rather than branchless, since it's not the only mode that triggers the credits.
Accepting!
