The discussion in some of the other threads about magic and it sizes in gaming had me thinking about more systems that could have magic being utilized freely by other class types, essentially. Classes in today's gaming seem to be driven by MMO archetypes that pigeonhole game design into an increasingly stale direction, IMO. I was just looking for some suggested examples of games that let you control a party, but also not be slaves to designated roles within that party. If that makes sense.
I think I agree with Octavius, in that by starting with a blank slate for characters but have a system where you then assign talents/points won't you end up creating the separate classes as the game unfolds anyway? This is specifically relating to the Party aspect of your thread as opposed to a single-PC game.
Also, by removing classes just because you're personally bored of them aren't you more suggesting that you're bored of the genre rather than the genre requires change? Most people here spend their time complaining if a game has too limited a class choice, do they not, and bemoan games which reduce class options.
I think whoever said "a bit like adventure games" is kind of proving this point. Like saying "wouldn't it be interesting to play an FPS that didn't have weapons + weapon variety/upgrades", it would be interesting, but it also wouldn't be an FPS.
I'm trying to visualise what a classless party based RPG would play like. I'm seeing 4/6/8 swordsmen walking along a beaten path. One loots a dead body and finds a wand of 10 charges of Open Lock. You give that to one of your party members, but it doesn't matter which. You loot another dead body and find a crossbow and bolts. You give that to another party member, but it doesn't matter which. Until all party members each have a wand of open lock and a crossbow. What I'm visualising is a diablo-clone bot:
