OGame Bodyguard

OGame Bodyguard is a new bot which is so far completely free, and appears to have more features than any other bot so far. It has possibly everything you will need from a OGame bot, including:

• Fleetsave - if an attack occurs, this bot can automatically send away your fleet and resources, as well as start production of ships to save any extra resources
• Automatic building and research - it can build a planet or a fleet all by itself as soon as necessary resources are available. It also supports simulation so you can see and calculate exactly what and how you want to build. Looks like it has everything OGame Planet Builder was supposed to have (which is discontinued for some time now).
  
• Auto attacks - OGame Bodyguard can send attacks and farm planets even when you're not around
• Fight simulator - it can can simulate attacks so you don't have to use any other programs for it. Although it's risky, you can also use it with the auto attack feature.
  

OGame Bodyguard supports all localized OGame versions, as well as multiple accounts, meaning it should be safe to login with more than one account as long as they are on different universes. You will most certainly be banned if you play two accounts in the same universe with this bot. It does have an overview window which clearly shows production and resources on all of your planets, as well as a feature to manage your messages. I tested the automatic building and it worked fine, and it doesn't appear to be stealing your passwords which is always a good thing.

OWaechter - OGame RSS Reader

Unlike OGam3r RSS Reader, this one is free, but only works on ogame.de.

The program will conveniently nest in your system tray and notify you of any scans, transports, attacks etc.

There's also a number of features planned like battle report archives, startup options, remote warnings and more.

I hope it will work soon on ogame.org and other localized versions. You can check OWaechter website for more info and download. There's also a forum available if you have any questions.

OGam3r RSS Reader

The OGam3r RSS Reader will retrieve your ingame messages via RSS feed, and notify you of any events, such as spying or attacks on your planet.

You can check here to see how it looks and read more about it.

It would be nice to see some other features, like sending emails when you're being attacked, or status of production/research or similar. Or at least combine the author's other project, OGame Ninja Timer with this.

Of course, it's not free: you'll have to dish out $10 to use it for 3 months, so it may not look so appealing, but if this is something you've been looking for, you're welcome to check it out.
I can't try it out so I got no idea if and how exactly it works, so don't blame me if it turns out to be something you didn't expect. For any concerns you might have I recommend mailing the author and asking him.
