@Rek: Your wordmark logos remind me of taking a train ride home recently, where I noticed a lot of graffiti on the tunnels. It was really interesting to see the various shapes and sizes it came in, and how nice a lot of it looked, compared to your average tagging around cities. I feel like having a deeper appreciation for graffiti would be a good place to start in learning how to design incredible logos.
Graffiti is a wealth of experimental letterforms, largely untapped by industries not related to graffiti culture.
This is misleading. The conventions of video game logo design, especially when it comes to 8-16 bit era games and those that seek to emulate them, are not the conventions of the modern mainstream/corporate logo designs you will find on sites like that. In fact, they are virtually the opposite. Where retro/pixel game logos employ tonnes of gradients, 3D/bevel/shading, jumbled letters, deformed glyphs, tight/squashed tracking, mismatched type styles, overlapping elements, high contrast colours, multiple outlines, etc, simultaneously, modern/mainstream logos shun them in favour of flat simplicity.
Even modern video games seem to exist in their own world when it comes to logos. The few that aren't overly rendered and textured tend to be tightly tracked sans serifs or geometric typefaces (with a modified or substituted glyph, if you're lucky). Comparable to action/scifi movie title design, I suppose.
