It's definitly a good idea working with BlackInk on games for several reasons:
1. you get a different style. When I work with photoshop/another drawoing program, I usually get realistic images, that almost have the same look over and over again. Using BlackInk I get my desired style every time. +
1.5 you can easily recreate that style by saving your pens and reusing them for the same purpose, for the game I have a base color pen that only changes color, a shading pen that stays exactly the same, an outline pen, a highlight pen, a detail pen and a shadow pen(plus a fire pen for one use) since you can change the settings of pens you can almost anytime get your desired result
2. you can draw very rough, since you can scale down almost everytime over 400%, since BlackInk works on such a huge scale. That erases many small flaws on the fly.
3. it is still being developed. That seems not so good does it? But it is, I had no crashes yet though I know others have, but for me it runs stable, but the greatest thing about it: you can suggest what you need and if it is reasonable it is normally added to the todo list, which has the possibility to improve your workflow very well.
