errr bodog....the difference between 200 and 250 ping is minimal....
Bodog, CSS is actually relatively playable at 200 ping because you aren't hopelessly disadvantaged like you are in RO. The game will never look pretty when you have a quarter of a second delay in it but the fact of the matter, you can play the game competitively even with a 200 ping on CSS because the netcode is far superior. You have to remember though, there is only so much you can do because you are trying to pretend 0 ping when one player might be pinging 10 and another 250, that doesn't change the fact that the netcode of the source engine is by far more advanced.
RO is basically unplayable at 250 ping, you have to aim 15 metres in front of a moving target, the opposition has a massive advantage. The predictions you have to make are enormous, you do realise that ping changes during a game based on a number of factors. You can ping anywhere from 10-40 ping difference sometimes, this cannot be assumed so again, you are arguing the unarguable.
R02 will be popular for a short period and then if TW actually actively follow up the game with patches and improvements, then the title has a chance at being played for a long time. Remember how far the distance from UK to Russia is, for example, West coast to East coast US will give you 100-120 ping, lag compensation would be most helpful here. For example, Sydney to West Australia, Sydney to New Zealand, Lag compensation would be a great addition to RO. Ultimately, I understand that TW will not include lag compensation as it would cost them too much to implement as they are a small team and don't have the same resources that Valve or activision but that doesn't change the fact that the game would be better as a result.
