200+ Area Control and Worker Placement Mechanics!

It's my birthday, so I thought it would be nice to do something special and crowdsource a big list of mechanisms! These apply to either area control games or worker placement games as triggers for special actions. Peruse this list next time you need some inspiration for your game design. The bulk of this list came from my twitter followers, which you can find on this thread. Thanks, tweeps!

If you ___ [this space/area/territory], do [action].

1. enter
2. enter from the north into
3. enter from the south into
4. enter from the east into
5. enter from the west into
6. leave
7. leave empty
8. go north from
9. go south from
10. go east from
11. go west from
12. complete
13. start the turn in
14. end the turn in
15. start the round in
16. end the turn in
17. start the phase in
18. start the phase in
19. start the game in
20. end the game in
21. destroy
22. destroy an area adjacent to
23. have simple friendly majority present in
24. have simple unfriendly majority present in
25. have more present than all other players combined in
26. have least presence
27. have no presence
28. have an even presence
29. have an odd presence
30. enclose
31. complete an enclosure around
32. become adjacent to
33. buy from
34. buy from an area adjacent to
35. sell
36. sell to
37. sell from an area adjacent to
38. build on
39. built on an area adjacent to
40. create
41. are pushed out of
42. farm on
43. harvest from
44. are part of a group on
45. are the only one on (meaning your one pawn is the only one present)
46. are the only ones on (meaning there are multiple pawns, but only yours)
47. fence
48. completely fence off
49. connect
50. join the longest connection to

You can quadruple this list by adding the following conditional modifiers

• are first to...
• are last to...
• most recently...

And with that, you have 200+ different area control or worker placement mechanisms! By no means comprehensive, but maybe they can shake loose your designer's block some day.
