Phoenix Deep Space Resurrection.

Yep that's the one - just managed to scare up some more shots too - I'll add em anyway
*passes the controller*
Your go!

50 hours in, feels like I'm still just starting.

Yep.

Just a hint; next time don't have Jelkala in the map. That gave it away. :)

Lemme think......

Hm....
Okay, this particular game was an Xbox exclusive and in my personal opinion, THE greatest Xbox game ever made. The setting is unique and so is the gameplay (Considering most games in my decade...), plus the story is decent. And dammit to hell I still cant get it to stop registering on search engines. Oh well.
(Pardon what I did to the game's pic, I was trying to make it not searchable on certain engines)

I believe that game is Breakdown. I remember hearing about it and the first person fighting mechanic, but never got around to playing it.

Didn't work very well.

Oh he's right, I have the original game lying next to me.
Very strange but cool game.

Only took 2 hours. OP is probably as upset as I was when my Cyberbykes was guessed within minutes. I thought I was the only person ever to have played that game.
And then I posted it again when I was drunk. Oh woe betide me...

Heh. The best defence against image searching is to take the screenshots yourself - you're very unlikely to get the exact same shot that's already up elsewhere on the web, and image searchers generally only find the same image (even if manipulated), not ones from (even slightly) different angles or with different poses or formations. Also cropping out UI elements where applicable (but many have already learned that lesson).

The reason I was able to guess Cyberbykes is because I'd played the demo on a PC Gamer disk, and it stuck in my mind.

As for making stuff non-searchable, I usually tinker with the image until tineye no longer recognizes it.

Oh no, I don't use image search as that would be no fun. I'm just pretty knowledgeable when it come to console games both mainstream and obscure ;) Now when it comes to obscure PC games, that's out of my range.

This next one is all Greek (and a little Japanese) to me...

It looks a lot like a NES title I own called "The Battle of Olympus".
