That's true, if you have some old games that you have an urge to replay, but no older machine at the ready, give the wrappers a try. For most games there's a either fan patches or a combination of compatibility settings plus wrappers available to get them running on modern machines (for many games the biggest hurdle is running the old 16bit installer executables on a 64bit OS).
But IMHO it's worth the hassle. The late 90's/early 2000's era holds many gems of gaming. Part of it is surely just my nostalgia (having been a easily impressible teenager in those years), but I also think that the gaming market was objectively more diverse in those years than today, due to some favorable combination of circumstances.
Hardware capabilities were growing in big leaps, but game development was still a relatively small business that didn't require multi-million dollar investments up front. So many small companies could push out new genre-defining games (and even more turds) with relative ease. Fore reference, I-War up there in my post had a development team of 6 people, but they produced a game that was up there with games you'd consider AAA (if that rating would have been used back then).
