That's exactly why I mention it. To me a game that is based on purely MP merits NEEDS a free weekend to check it out before buying it. Even if that weekend offers access to everything and starts right when the game releases, who cares? It's just 1 weekend. The thing is, the longer this weekend doesn't come, the harder the noobs are gonna run against a brick-wall of difficulty that no "noob only" server is ever gonna fix.
The longer it takes for them to offer free demo or free weekend, the less chance they have of getting more sales.
