...so please give me a laundry list of things that you enjoyed about old MMOs that I can respond to with Guild Wars 2 bullshit.
I'm just waiting for some real reasons that don't harken right back to nostalgia. It's either
1. Self admitted nostalgia. "Nothing will be like my first time."
2. Manchild nostalgia that doesn't own up to it. "I want to feel like I've never played this before even if that's unreasonable, but I won't admit this."
3. The deep denial of nostalgia that turns into hatred of refinement and advancement of the same concepts minus the old bullshit. "I'm Ruzbeh."
4. A longing for sandboxy elements. However, sandboxes still get released, still exist and carry on, and more sandboxes are on the way. Go play these instead of bitching.
5. Economy and crafting was better on a smaller scale userbase.
And this last one is the only interesting debate I've seen. Allowing more people access to crafting or making craftables and items more widespread, the economy changed. Some people want a system where you can't repair damaged items and must replace them, making crafting those items worthwhile. These sort of time limited items aren't going to show up in a mainstream MMO because they become an annoyance to many and don't vibe with limited playtimes. So this is an actual interesting take since it involves actual questions of systems and play that aren't simple refinements without loss.
That's different than some asshat bitching about LFR when there's still hard versions of the raid with better item value loot. That just becomes a childish rant that other people can see content that you used to think only special little you could see. It also reveals that MMOs weren't ever really challenging in any skillful manner. There just challenged your patience through heavy time commitment. When the artificial time extenders vanish, all that's left is the content.
