First of all, hi to everyone. I'm new to the forum but I'm also a die-hard fan of the RPG genre (both p&p systems and videogames). So I guess this's gonna be an easy "cohabitation".
Now, let's cut to the chase: I loved IE games, (before them I loved Darklands, that - I suspect - influenced a LOT the way you designed Storm of Zehir, Obsidian guys :D), I loved Myth, I love Total War, Company of Heroes and Dawn of War games...In short, I have nothing against tactical real time combat systems.
Still I consider turn based combat the best choice for RPGs. Why? Essentially because RPGs are games where players are supposed to handle with a small number of characters (4 up to 6, usually) with an huge amount of abilities/skills/spells (in comparison with war games). So, a lot of micro-management is need in order to "correctly" use those abilities, and so, a lot of pauses are needed in order to do that.
The result is a combat system that doesn't offer either the fluidity of a RTC system and the complete control over the action of a TBC system.
Now, I know you guys have a lot of experience with tactical combats and I'm totally sure you considered all options, but are you totally sure that TBCs aren't the best choice for this game? If yes, why?
