Graphics remind me of Excelsior, but the text at the bottom doesn't fit at all...

So no idea :)

- It's a strategy game with rpg- and businesselements

the new screenshot contains one hint.

Rings?
Sonic the Hedgehog! Has to be! Yep!

Rings of Medusa

i've used for this one well known site, so i'm cheater ;(

of course it's Rings of Medusa... Thought it's well known :)

i've played this game on Amiga

----- spoiler, close your eyes -----
and i have used Google to find title for this screendshot, i don't know if Google will help to find title for every game screenshot from game but it is possible, u have to only copy screenshot url to images search field
-------------------------------------------

i wish this game for PC (btw. if GOG use DOSBox for old PC games maybe they could prepare package of Amiga games with UAE?)

picture for you:

Didn't know Google did that. I searched by my avatar pic and got some very amusing results.

What about a little hint?

HINT HINT

The guy hasn't posted in 3 days, as his rep is still one since his first post. The screenshot matches the one on the page that you linked.
Go ahead and post a new one!

OK - I'l do the next one, maybe a little easier to get the ball rolling again.

This is not one of the best games ever made, did spend a few hours on it though.

I played it on C64 but the graphic from your screenshot looks a bit differently. I guess it's the same game, namely Bangkok Knights
