I think it depends very much on what your product does. E.g. in your case (games) bandwidth is a big deal. The last three companies I've worked at have all had AWS bills of more than $10M/yr and data egress costs were never more than 2-8% of the bill. A mixture of B2C and B2B SaaS companies.

In that case, the economics of bare metal aren't as clear-cut.
