How does giving some people the option to play a fast or slow game force other people to play the same way?
Imagine someone's sitting in the game browser looking for a pick-up game set at "normal" speed. All they see are a list of games set to "adrenaline junkie" speed because.
To put it another way, it has been my impression based on observation that the majority of gamers will always opt for the fastest speed possible in their games with the idea that fast games are more fun and/or they want to play many games in quick succession. I can remember way back when in StarCraft futilely searching for a game set to anything slower than "Fastest" (StarCraft had 5 game speeds, I believe). If Stardock/Ironclad introduced a super fast game speed, I could see that easily becoming the "default" speed for online games at some point in the future.
Now in my case, I don't ever plan on playing online, so this is all just theoretical for me, but those who enjoy this game because of its deliberately relaxed pace, I could definitely see them getting the short of end with this kind of deal.
Now, hold on, let's think about this. Obviously, all the gamers who like to opt for the fastest possible speed currently play on fast (a quick check of Ironclad Online shows that the games currently available are split roughly evenly between Normal and Fast). People do not opt for the fastest possible speed seem to be okay with the game as is, so we can assume that they either can find slower-paced games regardless, or like the game to be
exactly Fast, no slower, no faster. So, what happens when we add a new speed?
Well, first, the players who opt for the fastest possible speed switch to Very Fast. Note that this does not directly impact the community of players who like slower paced games in any way. In no way does this impact the people who's natural reaction ISN'T to turn the knob all the way up to the right. They couldn't care less whether the half of the games they don't play are Fast or Very Fast. The people who like to play on Fast and on no other speed will suffer from a loss of potential opponents, but the people who like to play on Normal seem to manage just fine, so I imagine they'll live, too.
One potential issue is that the "default speed" stance and the influx of new players (who, I would like to remind you, will be sinking their teeth into something they'd never consider trying before, and just might graduate from "Starcraft junkie" to "bonafide 4X gamer") could make looking for a game at a speed slower than Fastest like looking for a needle in a haystack. Fortunately, Ironclad, in their infinite wisdom, has provided us with an option to filter games based on game speed.
In closing - yes, a new, faster speed option would be great. And a slower one, too, just to provide some balance.
