The next mission was also a bit of a pushover difficulty-wise, albeit taking a long time to finish. I basically took the base in front of me immediately, and built my base on it. I then headed to the left, to swarm them and capture their base. It took a lil' save scumming to figure out the best combination, but I managed to make it work, overwhelming them. Interestingly, after their base was already destroyed, they rebuilt it, something I didn't know they did, but it didn't last long; already crippled, a second wave eliminated them.
From there, I had a minor resource disadvantage. I crippled their northeast base, but I couldn't destroy it. So they got to get the crystals there, but it was worth it, because I was getting my Guardian assault force (with Mutalisk assistance) ready. I took the base out before the geyser was depleted--heck, all of the northern geysers had a ton of gas in them, with the exception of that northeast one which was nearly depleted. The zerg apparently are supposed to use crystals more, given how much they used/mined compared to how much I did.
It wasn't difficult, but it was time-consuming. I've basically been playing for five hours for those two missions. I took a look at the guide for the next level, to get a feeling of whether I should start the level and put it away for later, or just put it aside.
...Quite the easy decision. Instantly, in my mind, there was one word and one word only coming to mind: "Nope!"
So probably won't do Starcraft again 'til next week at minimum, and probably will actually use said strategy guide. (I don't really use it that much. I'll use it to get the layout of the map, something which a little save scumming could tell me anyway, but that's about it. Unless I'm desperate. And given the mission description...I'm sure I will be.)
