There are only two of us now but for years it was just me and I have used SVN for many, many years.
Now we do all development in VM's (VirtualBox) and leave the source on the host and access it via virtual share/drive letters, never on the VM's. Source control is good old SVN with TortoiseSVN, all commits/update done from the host. We have an in-house SVN server with repositories for each projects, This makes upgrading version of Delphi simple, we build new VM's for new version of Delphi so we never have cross version compile/component install issues, because that never happens 😮 and use cloned repos for testing new version in new VM's before we ever move production code to a new Delphi version.
