Appleweed/Vegas Style

The purpose of this mod is to facilitate cash prize tournament through an in-game commerce service. This mod leverages concepts around [Distributed Gaming] and the [Meesha] implementation. For the first release, [PayPal] is used for secure transactions.

Basically, any DeathMatch game can add this mod as a mutator. Servers set an "ante" as an entry fee to play. The winner takes home the "pot"!

Why?

I'm very interested in creating commerce experiences within gaming. (Before anyone jumps to conclusions, NO, I don't want to create a 3-D store within a game!) Much of this interest has come from many years of game play, especially in Massive Multiplayer Online Role-Playing Games (MMORPG) like [Ultima Online] and [Everquest]. (For further reference, see "Inspiration", below.)

Also, have you seen [Ultimate Arena]? Pretty cool, but I wanted to be able to choose from the many different games created by the Unreal community of developers. And, hey, why pay someone else a commission?!

What?

There are two components to running Vegas Style games: The mutator and the commerce service.

Technically, "Vegas Style" is a mutator. It has the following features:

In-game currency called "Gibsons". (Named after [William Gibson] who you should all know, love, worship. )
Ability to set entry fees ("antes") in Gibsons on the server in order to play. (DeathMatch games only, for now.)
Separate and secure [CHAP] logins to commerce service for transaction management and player accounts.

The Commerce Service is a set of web pages. It has the following features:

Tracks in-game commerce transactions and player accounts. (i.e.: games, sessions, antes, winnings, reversals.)
Ability to exchange Gibsons for U.S. Dollars and vice-versa via payment gateways.
[PayPal] gateway. (Possibly others in the future: [Authorize.Net], etc.)
Session management featuring [CHAP] logins.
Player account management via web only. (This is purposely a security feature.)

Requirements:

UT2k3, of course.
[PayPal] accounts for each player and server.
LibHTTP

How?

... more detail here in a bit.

When?

Soon!

Future Plans

Move commerce service to [Meesha] implementation. (Account management will still be via web.)
Add more payment gateways, like [Authorize.Net].
Make Gibsons exchangeable with UO gold, Everquest platinum, and Star Wars Galaxies credits.

Comments

Foxpaw: Well, my two cents would be, when real money becomes involved people can get kind of serious about the game, and it can foster bad attitudes. From a technical standpoint, I think you may run into a different problem. You can make it hard for a person to decompile your source code and figure out a way to try and cheat other people out of their money, but you can't really make it impossible for them to decompile the sources. I'm not sure if it would be really difficult or not, but I would be wary of the security implications when people have the incentive of real money.

appleweed: Good points all around. We actually had a short thread on this on the forums: [Vegas discussion]. I see this mod for use with groups of people that know each other very well. In this case, I see playing UT for cash no different than playing a buck a hole in golf or a friendly poker game. I have thought of some ways to combat cheating, but this would be necessary only for anonymous tournament play. Also, in the end, whomever owns the UT server can pretty much determine the winner. It isn't a simple matter of protecting the code. (Tho, the MD5 checks do help.) One could easily add another mutator to the server that says "my buddy Tim always wins". However, noone will be able to simply login and steal your winnings. That has been protected using encryption, the fact that account information is never replicated and ultimately your PayPal account handles your cash winnings. More of this will be made obvious when I update the "How?" above.
