If anything MMOs have become too complex and too dependant on technology.
They need to go back to the basics, not try and make things more complex.
Leave FPS combat to FPS games.
Leave tedius and boring crafting with dozens of steps to real life and management games like the Sims.
Leave the min/maxing of stats and finding the most "efficient" ways to get to the end.
These are MMORPGs. Massively Multiplayer Online Role Playing Games.
The more technological and "complex" and "action oriented" these games become, the more they have to use instancing and zoning and other systems that take away from the Massively part.
The more "complex" and "action oriented" these games become, the more they become "niche" titles for the elitist MMO "hardcore" which takes away thousands, if not millions from the Multiplayer part.
The more I have to worry about managing resources and min/maxing my stats and the more I have to focus on number and mathematical efficiency, the less I am able to feel like I am Role Playing and the more I feel like I'm working or doing homework.
Just give me games that are fun to play, easy to get into, yet take skill and are challenging to master. Give me games that focus on the massively multiplayer part, the community and the vast openness of the world rather then spending all my time worrying about stats and managing this and that and doing homework.
Too many games and too many gamers don't realize that the thing their MMOs are missing isn't complexity, there is plenty of that in modern MMOs...
What they are missing is the fun. The adventure. The sense of discovery and wonder and camradiere and competition that comes from playing with and against other people in a massive online world.
No they are more focused on min/maxing their stats and finding the most efficient route to get the best loot and it's really quite sad what this genre has become.
It's incredibly sad that if you suggest things like taking away the loot and removing levels that people outcry "well what would we do then?"
