I have all the current skills (101 of 'em I think) and a brain capacity of 32. I got them all before upgrade cards came along. So... with the prospect of new skills on the horizon, how worthwhile will it be for me to expand my brain?
Will I need to get my brain to 102 to experience any benefit? Will I spend my imagination better buying learning speed cards? I'm just not real sure how the learning time works.
