F> Эээ?! А i+1-1+i или 1+i-i+1 совсем никак нельзя обойтись? Выглядит, кстати тоже ничего.

Valve Time is interesting ... And people get an idea of Valve Time because they're very used to how maybe other people work and bring things out. Other people have much more formalised schedules. They have dates they have like lines in the sand because of their structures (у Valve эти линии проводят, очевидно, на воде — Sinix).

...

The reason for that is because it's odd. ... It's actually not super important if this thing comes out on the Christmas where we said ... What's actually more important is ... it comes out in spring.
...
Because we're trusting the fact that when it takes longer, it will be better.
...
It's a high compliment!
