Yooka Laylee sold about 200k units across all platforms, and its score collapsed, so much for a game which cost about $3-4m to make. It's made about $8m or so in total, so we might see more from Playtonic but with less idiocy on their part after being burned by the hardcore which could've boosted those sales quite a bit more. But it's hardly in the realm of "being able to make more games off of the back of this" budgeting. This probably gets trimmed a bit more considering marketing budgets etc.
A Hat In Time by comparison was made on a budget of $260k, and just on PC is hitting the 65k mark as we speak, punting their current dosh to over $1m. It seems to be a slight sleeper hit and is now seeing more and more people buy it as the quality of the game gets out there.
