Since you asked...
The following sites are actually for independent web comics, but there is a large community surrounding these and many of these people and their readers are into computer games, RPGs, and the like. I've found many independent games through these, and there's a tendancy for news to spread on its own, so if your game is well liked by one of the authors, you may get mentioned on sites you've never even heard of. These are just the sites I know of, but if you find someone helpful within the community (and many are), they might point you to other places you can try as well.

I've never actually tried advertising anything with them before, so I'm not sure exactly how helpful they can be or what their individual policies are, but from what I've seen they can help bring in a few people.
There are also a couple of general game sites that seem to mention just about anything computer game related, so they might be a little helpful too:

There may also be a community out there that would like the strategy element of your game, but if there is I am unaware of it. There is, however, an interest over here in importing strategy board games from Germany (Settlers of Catan is relatively popular here), so a computer game equivalent may exist somewhere.
It is rather late where I am now and I don't have time to go through all my links to see who may be of help and who would just be a waste of your time (honestly I can't think of many more places that are indie-friendly), but I hope what I have provided will help you to expand your English-language base.
(judgeing by forums) This is a real shame and you wont get much of a market outside of Germany without it.
