probably not
I see the value in the following areas
- replayability
- enjoyment
- community support
For the first, games like SC2, WOW, CS, DOTA+Clones, RTCW/Q3A/UT all come to mind. Infinitely repayable with others. But note that its all with humans at this point. Playing comps in SC2 isn't the same as a person, and I can play a person on the same map over and over and never get bored. I'd pay 60 dollars for a game that gives me that kind of experience. Depending on the level of interaction, I would even be willing to pay a fee (WOW) providing the initial buy in cost isn't terribly high (ie: not 60 dollars)
For enjoyment, that can come from re-playability, but I'm thinking of the content of the actual game. For many games whose re-playability is limited (single player - stuff like Phoenix Wright), its about the enjoyment when you ARE playing it. I loved Assassin's Creed, I loved Mass Effect (Although you can really replay the game twice depending if you want to be good/evil but you ultimately don't change the story arc too much), HalfLife 2, Deus Ex (the first), but I can't play these game over and over (ie: > 3 times for some, >1 for the rest).
For the last, the more community support a game has, the longer it can last. Look at WC3 , look at SC2, look at basically any game that has mods. It adds a lot of longevity to a game.
For most other games I wouldn't pay more than 10-15 bucks. I played FarCry 2 for maybe 3 hours, but i just can't keep my interest in the game despite it being pretty. I would think most games fall into that category. Left For Dead was the sae for me (although others poured hundreds of hours)
When diablo3 comes out, would I be willing to pay 60 dollars for it? Yup. 70 dollars? Yup. 80 dollars? Wait for either many user reviews (media reviews are bs these days) or a demo...and then Yup.
Obviously it looks like I'm a blizzard fanboy...but the guys deliver.
If that new Deux Ex demo really captured the feeling of the original, I probably would have paid 60 for that. But as it is, it feels too empty and has no character.
I don't have time to play a lot of games anymore because I'm busier with other things...so when I play, I want it to be good, very very good. That is why I'm willing to pay - but I'm not going to buy in unless I know it will last a while. Kinda sucks for game devs, eh?
Despite this talk about lots of replayability: I'd pay 30-40 for a great 8-10 hour experience.
edit:
okay i wrote too much but this how it comes down to
lots of re playability and I will play it over and over: 80-100 dollars
a GREAT 10 hour experience that leaves me appreciating the game: 40 dollars
and i say this noting that i play about 04-10 hours a week of games on average....
therefore, because i don't play as much, i'm willing to wait for the prices to drop and then impulse buy things on steam
