Yes, almost every designer has a free rate, so you can use it to run a gaming site, if enough functionality. All such plans have limitations to a greater or lesser extent. Usually they are used to test the platform before deciding whether to pay for a paid subscription or not.
In addition to the reduced functionality, the most serious nuances of free plans are the impossibility of connecting your domain and the presence of engine ads in one form or another. If the first limitation is absent in some systems, the advertising is absolutely everywhere. Ditto with free hosting to install CMS, but they have another thing - little performance, almost all of them specifically slow.
If you need a normal clan site, which will be full-fledged, ie, functional, quickly work with high activity of the community, without advertising and on its own domain, the option is one - to choose the appropriate engine and pay the rate. Or hosting. Depends on what we're talking about, the designer or CMS.
Those who want to indulge, to try to make a site, look around, at first the free format may be enough and selected system. But those who want to do well, to take full advantage of the site, to position the guild properly, to fully interact with the community, need to take a paid plan. In general, this applies to any type of site. Free ones are good only for test-drives. This is a fact.
