Is it acceptable to post mini-batreps in here? If not, please remove this and I can rewrite via pm. If so, I'll make it brief.
Two games in sector 2/3 (1500 points), I'm more comfortable in sector 3, though, if I have to choose one.
First game: My Tyranid opponent heard of the horrors of the Nob biker list, and thought that he could take it down pretty easily. We argued this for a while, but he was not concerned. I wanted a campaign game, and didn't want to play the Ork biker list anyway, so I compromised and told him I'd play the most broken Necron list I could instead. My 1500 point list was two units of Warriors, the Nightbringer, and three Monoliths.
Sector: 3
Game type: Control Points
My opponent: Codex Tyranids
Result: Necron victory.
Highlights: Had I deployed more intelligently, using deepstrike for the Monoliths and starting the Nightbringer on the board, he would have had no chance whatsoever (the highest strength he took was 8 ), but because I began with the Monoliths on the table and everything else in reserve, it almost cost me the win. I immobilized one of my Monoliths on my first turn of movement, he immobilized a second on his first turn of shooting. The last got another turn or two of movement before he immobilized that too (we counted it up and he was rolling more than twice as many glances as he statistically should). To be fair, he had loaded up on Hive Guard, which did improve his chances somewhat. In the end, though, too much firepower was diverted to the Monoliths, and the Nightbringer swept down, killed some Hive Guard, took three wounds from shooting (he made none of his invulnerable saves) and managed to consolidate onto his control point, contesting it while my Warriors held mine. Game ended on turn 5, otherwise it would have been a draw.
Second game: Same opponent, but he agreed to play my Orks with a list I had written for them. Unfortunately, my Orks are a bit more competitive than my Necrons at this point, and the list I gave him did pretty well. At any rate, his army contained six Killa Kans, a Dreadnought, 60 Boyz with Power Klaw Nobs, a Mega Armor Boss in a trukk with 10 Boyz and a Powa Klaw Nob, a Big Mek w. KFF and 6 Wartrakks with twin-linked Rokkit Launchas. My list utilized 9 Destroyers, 3 Heavy Destroyers, 20 Warriors, 10 Immortals and a Lord with Veil of Darkness and Resurrection Orb. He agreed to play as my Orks provided I didn't play the same list I'd used against his Tyranids (I'd told him before that Orks had trouble with high-armor vehicles).
Sector: 3
Game Type: Annihilation
My opponent: Codex Orks
Result: Ork victory
Highlights: Luck simply was not on my side in these games. I won the last one from sheer ridiculousness of my list, but I had no such advantage in this game. Nine of my Destroyers spent three turns trying to put down one unit of Killa Kans, and doing absolutely nothing for two of those turns, and killing one of them on the third turn. A giant piece of terrain obscured my firing lanes, so I could only move my Destroyers in one direction, and not very efficiently at that. By the end of the game, I had killed one mob down to its last Boy and Nob, but the outrageous terrain made finishing the job impossible (it's a big hill which is about six inches tall and three feet long), I immobilized his trukk but had no opportunity to divert fire again and wreck it, and for the life of me the dice simply would not permit me to put down his Kans. By the end of the game I managed to knock out one of his Trakk squads, but he had claimed both of my Warriors squads (my plan to lure his horde to one extreme of the board while systematically using the Lord to move my Immortals and Warriors to the opposite side was crushed after veiling the Immortals, and then losing the Lord on his return trip to grab the Warriors...scattere d 12' off the table edge and then I rolled a 1 on mishap), as well as my Heavy Destroyers and he got credit for my Lord. So, end of the game, he had 4 Kill Points and I had 1, but was on the verge of 3. I don't guess there's anything I could have done, though: even with his Kustom Force Field obscuring all his vehicles, I still did nowhere near the expected damage, neutralizing my Destroyers for almost the entire game.
