Reviews hands down. Wii Play sold more than 3 times uncharted 2, and I can boldly say, that Wii play is nothing compared to Uncharted 2. Same with FE: RD. That got outsold by Iron Man the videogame, yet is of higher quality.

You could have at least lied and made us vgcharters happy by saying we're #1, lol

I hate niche games. The more a game sells under 2-3M the more my chances of disliking that game rise. Conversely the more a game sells over 2-3M the chances of my liking that game rise. That doesn't mean that I never really enjoy something which doesn't sell or will nearly always enjoy something which sells heaps.

My favourite shooter franchises are:

1. Half Life (10M plus)
2. Halo (10M plus)
3. Crysis (3M plus)
4. Gears of War (5M plus)
5. Call of duty (10M plus)

My favourite racing franchises are:

1. Mario Kart (20M plus?)

Well yeah, I don't see any reason to keep giving examples.

I know it's a better game, but I don't think it's that much better. Call of Duty games get incredible over inflated reviews due to hype. I mean Black Ops is a 4 hour long game, Modern Warfare 2 was 6, how can anything that short be taken seriously? Yea online is amazing, and co-op/zombie modes are fun as hell, but is Zombie mode in Black Ops any different then Zombie Mode in World at War? Except for the levels, no. Multiplayer isn't that different, thats why I haven't bought a new CoD game since Modern Warfare 1.

Thats why I said "sometimes I trust neither" because I don't think CoD is that great of a game, and I think the sales are over inflated due to popularity. No game this popular will ever get a score below 8/10, but the new IP Medal of Honor gets all the hate.

I am so oposite of you. RPG is my favorite platform, so let me give you examples.

Favorite RPG's

1. Mass Effect 2 (2.4 million)

2. Chrono Trigger (2.31 million)

3. Super Mario RPG (2.14 million)

4. Golden Sun (1.67 million)

5. Fallout 3: GOTY Ed in my case (360 - 3.48 million, combined - 5.93 million)

and this gen, Lost Odyssey, Too Human, and Tales of Vesperia have all been great hits for me, all selling under 1 million

Those aren't low sales. None under the median or even the upper quartile for that genre. Your favourite selling RPGs are only really eclipsed by less than half a dozen franchises from this generation at least.

See, you too really do like games which sell more, more typically. Though that doesn't mean that you won't find other smaller releases extremely enjoyable.

User reviews and a bit of critic reviews.

As for the sales argument: Carnival Games and Modern Warfare 2. Nuff said.

Reviews are the less evil of the two. Still, they're not worth much when determining whether a game is worth buying or not, well-written reviews just are nice to read.

Usually I can tell whether I'm going to like a game by looking at it, and then possibly seeking more information about it.

Yea, but I don't like some of the big titles like Fable, and I think games like Final Fantasy XIII and The Elder Scrolls are good, but nothing special. Also this generation, Lost Odyssey, Too Human, Tales of Vesperia, and Golden Sun DS all have lacking sales, none selling over 1 million, some only half.

I won't deny that generally high selling games tend to be well polished, and well good, but only about half my games fall into the high selling category. For example this fall I picked up Halo, Alan Wake, and Assassin's Creed, but I also picked up Vanquish, blur, and Front Mission Evolved. All of which I enjoy to about the same degree. How many units did Front Mission sell compared to Halo? Something like 130k, and Halo is approaching 8 million.

Well I go with what I'd find more interesting sometimes what I like might sell beter but not review as well but more often what I like won't sell as well but has high reviews.  Okami, Shadow of the Collosis and Bully stand out the most to me. However many of the games that have high reviews and high sales I'm not as interested in.
