Argh! How do you do this to me, Blizzard! After D3 I should expect that I would be immune to your wiles, and yet 15 years of absolutely loving your games has me thinking that maybe I should've pre-ordered this when it was $30.
Though I'll probably find the strength to resist this siren on account that I'm pretty sure they'll never deliver the game which I feel I should be entitled to expect from a $140 purchase (extrapolating to the third expansion based on the price of HoTS -- 60+40+40 $).
Which would be ALL non-hero units from the StarCraft universe in addition to new units from the sequel+expansions available for use in multiplayer by the time the trilogy is complete.
Because, good grief, WoL broke sales records, the complete sequel w/ expansions is going to cost $140 and you should humor old-school SC fans by including every single old-school unit from the first one in addition to the newbies by the time this all said and done with.
You say: but the hellion combines the vulture's speed with the firebat's flamethrower. And now the Hellbat builds on that to create a new walking, flamethrowing fiend.
I say: for $140 I should expect that all of them would be available. Give me the most viable builds ever seen in an RTS, damn it! I played that first game of yours for ten years, the least you could do is include all of the familiar faces from the first game alongside the new ones.
