Terran Siege

This strategy doesn't require all that much micro, but it can still be effective ;-).

BUILD OURDER:
-First of all, start out with your standard build order. I would reccomend building a Depot on the 8th SCV, Refinery on the 9th, and Barracks on the 11th; but that's just my opinion.
-Now, after you have your first Barracks done, build another. Make sure your constantly pumping out SCVs!!! I usually do 3 SCVs per Refinery and 1 1/2 SCVs per mineral, or just expand if the game permits.
-Your 2nd Barracks should be done. Take 2 SCVs and build a Depot and an Academy. Research U-837 (er whatever it is) Shells as soon as it builds; or if you feel a rush coming research Stims.
-Now you have most of the tech you'll need. Build 4 more barracks (the 6 Barracks are CRUCIAL! So don't skimp on them) and pump out your first dozen units. I usually do 9 Marines, 1 Bat, and 2 Medics; but then again, thats just me.
-While building your attack teams build a Factory (2 if minerals permit) and pump out Vultures to scout with. Depending on how desperate I am to kill my enemies I either wait for the Vultures or put 8 marines in 2 Bunkers (during step three) and take the other Marines scouting.
-If you found your opponents base, and they are going mass infantry, build Medarines/Vultures/Tanks. If they are going mass air (easier to kill, hehehe) pump Medarines/Goliaths.If they are turtling themselves in, build a lot of Tanks with Goliath (mass defense usually leads to mass air/mass drops) and Medarine backup.

ATTACK SEQUENCE:
-Now we get to the fun part, hehehe. Since this is, after all, a Siege the general idea is to make the enemy unable to move from their base. Although air units can get by, I doubt they would do much harm. Once you have your first 100 or so units outside of your opponents base, attack. And keep those reinforcements coming! Put your Barrack's and Factory's rally point right outside the base to save time. You should never stop building, no exceptions! If you're short on cash, expand, but this is supposed to be on a money map. If they are more on the offensive side then you may want to stage your attacks in waves, not just one big attack followed by reinforcements every 30 seconds or so. If all goes well (and if you're fast enough), the game should end at about 17-20 minutes.
-If you are the kinda person that likes micro - aren't we all? - then you can mix in Ghost, Sci Vessels and Battle Cruisers. Although this will prolong the game, in most cases it garantees a win. I've only tried it this want once and I didn't believe that all that extra micro was worth the win: I can stand a loss every once in awhile.
