Look, in a turn-based RPG, with a small number of dudes fighting a small number of dudes, there isn’t much in the way of tactics that is possible. The math isn’t there! I think you’re wanting something closer to chess. Sure, chess is complex, but that’s sixteen pieces on sixteen. For a single-player RPG, the fun is in the story (on a high level) and the stat building and lewt finding (on a low level). The combat is a means to an end. So make it fast and lively, end it, and get on to the next fast, lively combat. I do put in fights with odd tactics, generally weird or boss encounters. It’s nice variety. But combat is still the means to an end.
If you really want tactics in an RPG, play chess and give your pieces cute names. Like, “I declare, forsooth, that Queen Zzelma, my 18th level Rogue-Paladin, doth move 4 spaces diagonally in defiance of the Darkbeetle Empire. Hark, she hath slain a Knight, and is thuseth Level 19. Huzzah.” Chess is about quality. RPGs are about quantity.
Sadly, I haven't gotten any angry E-mails about this yet. What's the point of giving good flamebait if nobody bites? Even if I absolutely believe that what I said is true.
When designing a game, you have to keep your focus on what makes that sort of game cool and resist the temptation to bring in stuff that dilutes your focus. When I write an RPG, I try to put in about eight or nine serious, tactical encounters with thought involved. The rest of the battles are quick, light, kick-ass, adolescent power fantasy stuff. Because that's what makes the genre work.
In my favorite RPGs in the last few years, like Mass Effect and Fallout 3, most of the fights involved shredding bozos. And that's the way we like it.
Edit: Happily, a commenter pointed out I missed a forum discussion where I am subjected to the withering rage of the Internet. I don't understand what makes some people so angry about things.
Actually, I should point out I plan, in my next game engine, to highly refine both my graphics and the tactical elements of combat. There IS room for improvement. But that doesn't change the fact that if you demand serious tactical experiences in your battles, stay away from RPGs. Mine. Anyones. They are not for you.
