maybe like a said I am not lawyer, I am just a peaceful person :)

for audio/visuals the game is currently pretty basic because I am not wearing all the game development hats, and 3D graphics/audio/animation is not my favorite things (but PR queue is open if anybody is interested), but it can be scaled to more complex map, I actually convert old "real" dust2 map to this game a _year_ ago and record video of playing it https://www.youtube.com/watch?v=aIBVGZanVvU

This is a much better demo! Thank you for the link.

thank you, no problem, I was recording videos as development was going to record progress

I think all he is saying remove the references to „Counter-Strike“ and you are all good! How about Sol-Strike? ;)

that actually sounds kinda cool, but do I have a permission to use it from you, or now anybody can trademark it so I have to be first to register in German with GmbH or smth :D

Trade mark law usually requires that a mark is not descriptive - counterstrike is a dictionary word that describes fighting back against an attacker. Seems perfectly fine to use in any fps game.

Can't see how that trade mark could stand against a challenge (in UK/EU)?

See eg Art.4, Art.7(1)(c) of EUTMR.

IANAL, these are my personal opinions and unrelated to my employment.

I am also not a lawyer, but I would not like to step into a trademark dispute just because it 'seems perfectly fine'.

Albeit in this case you're most likely to just get a cease and desist rather than getting sued.

ohh, date with Gaben incoming

Yes, you wouldn't want to use "Counter-Strike" but legally they can't stop you using "counterstrike". As you intimate, the legislation probably doesn't matter if you can't afford the legal process.

counterstrike by itself might be OK although not used as branding, but none of the stylized forms could be used - that's my understanding at least.
