I'm not sure about that. What difficulty are you on? I restarted my CI games many times, with most ending in month 3 regardless of the strategies I took in the base. Not saying you're wrong - I just didn't notice. I'm using that stategy on my current game, so I'll pay attention this time.
@Bremenacht - Yups, also I found that not researching the Xeno Biology straight away left me with easier missions. If you ignore the priority missions the game takes a little longer before that first terror mission.
When I was doing well and had a bundle of cash, I filled the base to see if there was an achievement for it (there isn't). I had about 7 or 8 workshops, I think, and got a 10% rebate.
The last point I'd like to make is that having a blob of 4 workshops is essential for the beginning of the game, getting back 28% resources from engineering tasks really does make a huge difference. Question though, if you make enough to get 100% back (not that I would), does that mean you get back things like alien power sources etc?
Finished CI the other night. Before the end, I had a spare heavy so I sent him off on that Solo achievement and almost got it. The Ethereal, Heavy Floaters, and all but one Muton were dispatched. This last Muton had been mainflayed twice and possessed three times, so he was putty. And yet, the fucker developed super-snipe powers and offed my heavy in three consecutive shots. Bah.
Throughly enjoying Impossible at the moment. They joy of being able to reload a pear-shaped mission. This game has legs.
