Peer-to-peer MMORPGs could theoretically work cheaply and efficiently in regulating server load, but practical issues such as asymmetrical network bandwidth, CPU-hungry rendering engines, unreliability of individual nodes, and inherent lack of security (opening fertile new grounds for cheating) can make them a difficult proposition. The hosted infrastructure for a commercial-grade MMORPG requires the deployment of hundreds (or even thousands) of servers. Developing an affordable infrastructure for an online game requires developers to scale large numbers of players with less hardware and network investment.[26]
