This is about as good as I've seen on any commercial classic game compilation. I'd agree that most of the free emulators are better for the various options they have (filters, save states, even the menuing systems for some of them), but the emulation here is quite accurate. The only complaint I have is that color palette is off a bit on a small handful of Atari 2600 games--I'm certain 2600
Asteroids has the wrong colors (might be the PAL palette rather than NTSC).
On the positive side, it works extremely well, with in-game manuals, and the emulation speed is excellent. One other positive aspect that you may have overlooked is that it's very easy to get this up and running. Most "downloadable" emulators require the user to go through various tweaks and toggles to get it running acceptably, but this one ran properly (full screen graphics, proper sound, proper speed) the first time and every time.
The menus are a bit clunky, but the retro stuff is fine. There's more historical information in this compilation than in most of the others out there.
I don't know what you meant by it taking "a lot to install in your computer." You don't even have to install it at all--you can run it directly from CD (a rarity in today's market). If you do prefer to install it (for convenience), then it only takes a few hundred megs at most (if you install everything). Unless your computer is barely scraping the minimum requirements and you're starving for hard drive space, I can't see this being a concern.
You mean great games like
Adventure,
Missile Command,
Warlords,
Super Breakout,
Yars' Revenge,
Gravitar, and
Millipede aren't on here? Oh, wait a moment...they are!
While I agree that Activision also produced some of the best 2600 games, that's what
Activision Anthology is for. Namco didn't produce any games for the 2600 themselves--they just licensed a few of their arcade games for conversion. While those games are great in their own right, the point is that this is supposed to be an
Atari collection, so people are buying this for
Asteroids,
Breakout,
Centipede, and some of the others I named above, and maybe to revisit some of the less popular (but still fun) games like
Canyon Bomber,
Dodge 'Em, and
Human Cannonball.
I'm not sure why
Indy 500 and
Solaris aren't on here, though...especially
Solaris, as that's considered by many to be one of the 2600's finest games (in graphics as well as in gameplay). Oh well, at least that'll be on the Atari Flashback console. Anyone who picks up that game is going to be in for one wild ride. If Atari wants to score bonus points, they'll add those games (and
Saboteur) to the PS2/X-Box
Atari Anthology discs, too.
