Hello Joao,
With the Agile Platform you can build any kind of websites, even the more complex.
You can build all the kind of elements, part of web development like HTML, HTML5, CSS, Javascript, JQuery, Web Services, C# or Java extensions(depending the version you're using) with methods to extend the platform functionalities and so on..
Good luck on your project and any doubt just ask the community..

Kind Regards,
Gonçalo M.

It basically has a account system with registration, profile, firends etc... deposit/withdraw system for players who want to deposit money and then withdraw their earnings, skill rating system that retrieves data from a gameserver and then  determines the skill of a player, wallet/bank system to display the available cash of a player to withdraw and a score reporting system to see who won and who lost...

Based in your description I'll say that it is not the best project for someone to be introduced to OutSystems.
You'll have to do a lot of external development like the formula for calculating user experience, the webservices communication to the several games... But if you already have that part done and are analysing a migration it will be easy for an experienced developer. Registration, friends, rankings, wallet... are all easier to do in OS that in regular languages.

So, following the same logic, if the site is well planned and everything that will be needed is detailed, why not? About the time, it really depends on what you want. Find your programmer, show him/her your idea and ask for an approximate number of days. It may surprise you.

Yes yes, the skill rating and score reporting are things that come from the gameserver wich can be done separatelly, so the OS can do the wallet,account system and stuff..

Hello, João. You can build any sort of website with the Agile Platform. Checkout pordata.pt or fly.com, for example.

Here at OutSystems we're proud to "eat our own dog food". We create the platform we use it to build our webapps :)

Regarding your project, if you pick the agile platform, I'm sure that any roadblock or any question that you might have, will be helped and solved by our community!

Cheers and good luck with that promising project!

I really missed out on the obvious. As Miguel stated all these web properties you see are built with the Agile Platform, from website, to community, to the network. This, along with dozens of internal apps for several different purposes.

One of the great things about the platform is that you can use it to quickly build a standard enterprise application, but also, start from a blank canvas, and go wild from there.

Join the fun!! :-)

The must obvious and nobody remembered to mention..lol..
Well done Gonçalo.

Add to that list of websites the original sites at https://www.edpsu.pt and https://www.edpdistribuicao.pt. They've since been redesigned but originally they run on top of the OutSystems Platform.
