Brian's not the only host to voice this concern. I have seen this same argument voiced in the past.
The only difference is that in the past, the player base in southern Ontario (toronto region) was much smaller and the difference between TWO games would make or break a host's planning strategies.
Now that the player base is so huge, we can afford TWO games on the same day, given that one is a skirmish-based game and the other is a milsim. When a THIRD party shows up that encroaches on either one of those two gaming ideals, that is when further issues pop up and I do understand Brian's concerns with this issue.
In the end, it is up to the player to decide which game to attend, but as hosts, you all must come to some sort of executive decision to play nice with each other to help each other out.
As a host, you hold a further responsibility above the "regular player" and you must begin to assist your fellow hosts as well.
That's just my point of view and I hope that this discussion brings forth further compatibility and pre-planned gaming events that will accomodate all player bases across Canada.
