Making an annual salary + bonus of $300K at a mobile games studio, in Boulder CO is pretty impressive. Counting stock though is always a bit dicey, especially if you coded through the 90's :-).
On counting stock: It's a big public company I'm talking about, a modern blue chip, so the stock will be worth something.
But I'm not counting it right now, regardless. The cash part of the offer is entirely enough to keep me happy for each of the first two years, and the stock is a bonus.
Starting in year three, though, compensation is nearly half stock. I did code through the 90's, so I'm going to take any stock valuation with a grain of salt. I'll reevaluate my options at that time, if I decide to stick with them for that long.
