I like the map setup, making it part defense, part minigame (like how Marioparty is part boardgame, part minigame), but sadly, all your minigames are minigames that have already been done by taking the minigames from other maps
(sport maps, Mario Party and Mario Party 2 for SC, Random Fighters, Dodge *whoever*, Dt tag, Lurker Dodge, and Sniper maps.) Although I like these games and mini-games that I have played (that have ALL been made for SC), it lacks originality. Now, I'm not expecting you to "magically" invent all new never-before-seen minigames; just ones on Starcraft! For example, all the famous mini-games on the actual Mario Party series.. revamped!
Now this whole post above would be worthless if I just left it at that, so of course i'll help you with some minigames!!!!
Some minigames from the Mario Party series that I have never seen before on Starcraft are:
Cast Away: This is to all you N64 fans who bought the first Mario Party! This is a 4-player FFA It went like this: there were 3 rows of goodies that went right to left or left to right. You would pull down on the control and well.. Cast away! Depending on how much pulled down before releasing, how far your arm would go. You would have to time WHEN you released it to have your hook (a sticky hand) grab the item. Then, you would have to rotate the control stick to reel it in. It was a 90 second timer and there was no "winner"; it was a bonus round.
To replicate this, you would have men walk on the ground, some going from left to right, and some going right to left. You would then have some "power meter" by which you could choose which of the three rows you are aiming at. Then, depending on which row you did, you would "launch" a certain unit at the row. (The timing sequence was somewhat the same for each row, so you would have a slow overlord for first row, a slow scout for 2nd row, and a scourge for 3rd row.) Then you would have something like make them move a fast overlord back to their location or something like that.
Platform Peril Ah yes.. an old time favorite for those who've played Mario Party 1 or 2. IThis was also a 4-player FFA. You would run up ISOMETRIC (lucky us) terrain and you would have to constantly jump the gaps in the platforms. While doing so you had to dodge pyramids that happened to appear on the platforms. Also, some platforms were odd conveyor belts that pushed you toward or away from the next platform, destroying your jump timing. The winner was the one who reached the end platform first, while the rest.. well.. fall
.
Although I don't know how you could make this jumping mechanism, you should have an area behind them or overlords coming up towards them making it that they can't lag behind. I think you should use pylons and have them be moved by triggers or by observers, forcing the players to move left and right. You could also have some sort of "suck", making them drag towards the overlords. That way, you can have the mini-game take up little space while still making it long.
When I write these mini-games, I can't help but think about the other mini-games people have made in Starcraft, like DDR and Starcraft Party 1 & 2. They sure are fun.
