Diversity of opinions is a good thing. I'd still rely on tag combinations for refining a search. That's how a lot of my stuff gets found.
Viewing post in Problems with the "3D" tag
Not in regards to words and their meaning. If we have "opinions" that differ on the meaning of the very words we use to communicate, misunderstandings are bound to happen.
For instance, 3d can also mean stereoscopic. Or that the 2d images are rendered in 3d.
3d is one of those tags that work better with combination.
Then answer, how can I find through the search games that have three dimensions? The genre of the game doesn’t matter to me, it doesn’t matter if the game is played in first person, third person or second person. It doesn't matter if it's a simulator, a shooter or a strategy game. All that matters to me is that the game be three-dimensional.
What combination of tags should I use for this?
