Right...well, I won;t argue any more on this (we both have our own opinions anyways, no harm in that), but just to reply on a few issues;
1/ I don;t think I've ever seen a photo-realistic tree in a 2D
game. And IMO the likes of tress in Far Cry, etc (and this is the level which RTS' will reach) aremore than good enough.
2/ Vertical movement is extremely useful for more realistic line of sight, as well as stuff like (obviously) aircraft. for example, being able to launch low-level bombing raids (improved accuracy, greater risk) vs high level (lower accuracy, less risk). This would be very hard to portray in 2D IM
3/Isometric view can easily be done by a 3d engine. It's a simple process of translating abstract 3d points to 2d screen pixels.
4/Free camera is vital IMO in 2 ways. firstly, immersion - it allows you to get visually involved with the battle. Even though it's cosmetic, it's still useful. Secondly, it makes it far easier to judge subtle terrain differences, like slopes. and thus to implement and use them as part of the game mechanics.
5/ (finally) any 2D game will be based on flat images. Thus, there's no natural way to calculate the lighting - to diffentiate between an arm and a leg, for example. On 3d models, each facet's lighting can be naturally calculated- meaning realistic shadows and light casting.
If I felt 2D RTS games had
any advantage over 3d, I'd expect someone to still be making them. As it is, they are becoming fewer and fewer, and the likes of
Medieval are forging forward. I think this is simply because 3d is more realistic - you can have proper slopes and terrain features which are clearly visible to the player, and which have built in properties (angle, surface type, etc) as part of the geometry. In 2D, this is less implicit and has to be added in and conveyed through some other means.

The trouble is I've yet to see a quality isometric game in recent years, I know everything has switched to 3D - but that doesn't alter the fact that the last one I can remember is C&C: RA2 which looks pants. I mean granted everything was bright and pretty - but these days people expect a lot more. There really shouldn't be any excuse for RTS games to feature full weather, day and night cycles, deformable terrain, tunnels and so on in game - it's the logical step to take when considering you're pitting two sides against eachother in a contest of strategy.
If I want to hide people in that house - I should be able to. If I want a guy to climb a tree and sniper - he should be able to. If I want to take out that bridge / tower / fence / whatever - I should be able to. If I want to mine roads, place claymores and so forth in buildings as a trap for enemy units - I should be able to. There's so much scope for tactics in war games, but things have barely been tapped.
I think the closer you get simulating the real world - not just the AI, but also the environment (0which is arguably more crucial), the closer this sort of thing becomes. That's why I prefer 3d - it's just better at that sort of thing. The real world is 3d too - it translates well.
