I was tired and bored last night, looked at the games in my origin client and saw Battlefield 1942. I never played online, launched it once or twice, but, damn, compared to BF4, we have come a loooooooooong way. But yeah, BF 1942 was released in 2002, so ~13 years. But nice to see how things have evolved. Will the difference in another 10 years time be as drastic as the last 10 years have been?
I think the further we go, the more detail gets involved and so the processing power (and production cost by dev company) too.
