at least be possible to [...] change the peace, control settings and garrison and fleet orders.
Normally useless as a TCP/IP game should ask dinamically those things like in the FtF game.
Asking this "dynamically" would of course be better, but I also imagine that this would also change the game in a way that would make it different from a PBEM or mutiple players on one computer (haven't tried that mode, maybe it's already included?). I wouldn't mind this difference since that's something I like with the boardgame (leaving a corps that can fit in a city and allow it to retreat into the city, stopping at least one opponent corps from advancing through, as an example). And this would require more of a change to the game than allowing you to manipulate the orders using the same interfaces as exist in the game right now.
It would be nice if Marshall could share how he envisions a TCP/IP game? If it's just an integrated PBEM file processor that will allow you to view opponent moves on-line I think that would be a waste of time and the PBEM that exists in the game today will work fine. A TCP/IP game need to flow quicker and the only way that can happen is if you can prepare your actions in advance. Even in a game against the AI moving corps and dropping off garrisons takes time, especially sinc you don't have an indicator that shows the strenght of garrisons on the icon (include that on ships as well, as it would reduce the clicking time). Separating and finding corps with unit counters all the same size is also time consuming.
The game has improved a lot over the last two years (it is that long since it was released, right?) and with some AI work shoudl be even better in another year. But I do think the AI needs some "grand strategy" to be included. Before a DOW, the value need to be estimated. What effect will this have now on the PP scale? What effect will it have if/when you lose it? What can be expected in money, manpower or units built? Any other actions must also be measured in your army strength and Victory Points gained.
