I was surprised not to find OpenTTD on here. A very immersive game, much more so than Openrock Curling
Nice list. You were able to name two fine RTS games, but forgot the best one IMO:
http://springrts.com/
Only goes to show that there’s lots of free and opensource games that are worth playing.
Nice List these games are good but i think you can find better ones
Given the sophistication of its engine, and its superior and extremely scalable graphics, presence in the apt repositories, etc, I’m surprised that this list does not mention the SpringRTS games.
While most RTS games shackle players with unit limits and queue limits this limit that limit, the Spring RTS games are years ahead of such games as StarCraft. With just a few clicks you can start execute complex strategies. You can queue up hundreds (up to 9999) of units, order a constructor to build hundreds of different buildings, or order a factory to build planes that will automatically patrol a route as they roll off the assembly line.
The SpringRTS game Complete Annihilation has the perfect name. It is COMPLETE. Nothing about this game is half-ass: it’s like a videogame apocalypse. You don’t just order an attack — you send in a WAVE of hundreds of units, a wall of steel death that will fill the screen with awesome-looking explosions for minutes on end. You can build a nuclear missile capable of destroying a screen full of units, but it’s worthless to build just one: Typically, I send them over in batches of a dozen or more. Obscene? YES. That’s Complete Annihilation! Every game is non-stop action, carnage, and brutality at a level yet to be seen in other games.
Thanks for the comment. We have already featured SpringRTS in http://open-tube.com/30-open-source-games-great-game-play-graphics-and-more-for-free
It’s hard to be humble with ancestors like mine!
I’ve starcraft 2 beta, but all makes an attempt to make use of it have failed, I’ve tried ALL mac/laptop VMs, crossover, wine and the rest, all lead to the same error. So I’ll bide my time and wait for a mac version to be sent. Kinda inconsiderate to send a person who states they personal a mac a pc beta
. I simply wish they will launch the game quickly!
Hello
Despite the fact the beta is almost at the end of first stage, amazing replays will still be accessable for those who missed some important games!
I have been to your website before. The more I learn, the more I keep coming back!
