There are a lot of good comments and observations in this thread. It would be a shame to see SINS pass away, I've been supporting it with my nephews from the beginning and still love the game.
SIN2: Yes, please.
64bit: Yes, please, even if it is this same game without the memory limitation it would still be epic! that 400 planet Star Wars map would be more playable
Kickstarter: Yes, I would support.
Planet Annihilation: Its good, but its not as much fun as SINS. I think a right-click is missing to do upgrades. Regardless its still missing something. The original Supreme Commander and SINS are to the two best RTS currently and both are old games. In my view. SC2 was ruined by the new map engine, looked great but wasn't openDeveloper enabled; result no 2nd Add-on was ever released.
We all want SINS2 and maybe people, in general, won't pay just for 64bit and nothing else, so to encourage the ideas of the next RTS platforms maybe we do need more. I have been thinking lately about where gaming will be in 5 years time. The consoles have managed to get people out of thier chairs and standing, dancing, surf boarding and Jedi-Knight-ing but in the PC gaming world we are still sitting. Voice activition is getting better but even the Ocotolus Rift head gear still needs a keyboard. What about touch screens ? low refresh rates I've heard but a SINS game that could be operated across multiple monitors (Like SC) and touch screen would be cool!!
Have any of you seen 'Enders Game' the film, the main war scenes; Now that is an RTS I want, with full 3D movement.
