I've had a couple truly epic ladder games myself. One was a 45 min TvP on Scrap Station which started with him scouting my proxy 10 rax reaper, so after my first reaper I popped out 2 marauders with conc shell while making a beeline to banshees with cloak. My weak marauder crap failed, so I floated my rax back to my base and built 2 more to start pumping units for the inevitable counterattack. He sniped my CC that I had just floated down to my natural, but I just BARELY managed to hold him off at my main's ramp with some rax units, 3 banshees, and all of my SCVs. After that I harassed the shit out of him with banshees and got about a thousand probe kills to even things up. This gave me time to secure my natural and a third, and I eventually won the macro battle (in a big way; I had around 7k minerals and was making BCs by the time the game ended
) by keeping him on 2 bases. Cloaked banshees are SOOOOO strong on Scrap Station.
The other game was a TvT on Lost Temple that actually followed a similar trajectory of failed cheese -> cloaked banshees -> win via harassment and superior economy. It wasn't nearly as spectacular, but there was one pretty funny bit: As soon as he scouted that I had 2 port banshee coming, he threw down an armory and got a thor. I had an expansion up and he didn't, so I knew that if I continued to poke at him with a couple banshees every now and then, he'd get way too many thors and not be able to afford much else, while I could mop him up with marauders and tanks. And that's exactly what happened! I get really excited when I'm able to gameplan like that on the fly and it works out seamlessly.
Apparently the key to having really epic games is to (poorly) cheese a lot and then make a bunch of dangerous transitions. It reminds me of last patch when I played TvP on Steppes of War where my opponent went cannon rush -> DT -> void ray. Any good player should be able to own someone doing so many tech switches in the early game, but I was so caught off guard by all his funky deviations that the win was twice as difficult as it should have been.
Oh, and that TvT win got me up to diamond. I'M BACK
