Where are the Good Open Source Games?

I've played it, but I don't exactly know what to do in game. It's confusing. I tried reading the manual, but it confuses me further.

Both two Quake 3 mods turned into full-games (open source).
Pretty much awesome.

There's no real reason why more games can't go open source.

Most of a game's content these days is graphics which can be kept under a proprietary licence leaving the engine FOSS so it can be recompiled for any OS or architecture.

Maybe in the distant future, a pack of game developers could create an open source engine. It would have to be something like RenderWare, so it can be used for any type of game (fps, rgp, race, mmo, etc.).

At this moment, that's not the case at all. Unreal Tournament 3 was a forefront to sell the Unreal 3 engine, Crysis 2 to sell CryEngine 3, Half-Life 2 to sell the Source engine and the upcoming game Rage to sell the id Tech 5 engine. Epic Games, Crytek, Valve and ZeniMax make a lot of money licensing engines.
Although ZeniMax has of course released id Tech 3 before five years after Quake III Arena. So maybe we can expect the same with id Tech 4 in a few years.

Most open source engines are modifications of the id Tech 3 engine, or can't reach the technical level of previously mentioned engines. Like Cube 2 which is pretty good, but lacks decent physics for example.

While the source engine is not technically Open Source, Valve does freely give you the source developers kit, which can let developers build mods and even standalone games for free. I believe you can freely distribute your mods, but you can't sell them. But yes, licensing game engines is a major part of a developers income, its a shame when a very hyped games turns out to be more like a tech-demo, with garbage game play and no story.
