FreeSCI is virtually perfect, and there is absolutely no need for anyone to create a new one. Though the main release still only supports EGA games, they have background work on SCI even up to SCI32. It will take time to finish it, as it is also a free service/hobby project that has no funding. That being the case, the developers can't focus 100% of their time to it--they need to focus on their school and work and keep that as their priority. However, the developers at work on it are the programming elite with top notch skills, and they are doing a fantastic job. What it boils down to though is that it's a free open source project, so if you want it done sooner, you should join the team.
