GIANTS clearly feel the old equipment is important as when they had to make Lizard tractors they made old ones (thinking FS2011 where there were two old Lizard starter tractors and old New Holland and Claas-inspired combines), and every game since has started with old tractors.
If anything, I hope in the future the starting equipment is even older, from the 70s or earlier. It would be good to start with an old open top combine (one which was established in Western countries anyway, rather than Bizon) and perhaps some smaller bales and other small-scale equipment.
In dream land (for me) it would be good if there was a more progressive path, so you start with 50s or 60s equipment (a lot of people would go crazy for a Little Grey Fergie) and then you are able to progress through the 80s and 90s to the present day. Entirely optional for those who only want to play with modern equipment. Of course, that would be mean an impossible level of equipment from GIANTS, but it would be great to have the option to role play the building of a farm from an early stage through to being a thoroughly modern affair. Perhaps one day.
Personal wish list: Massey Ferguson 500 combine, MF35 or MF135 tractor and a MF30 seed drill (draw bar, not 3-point linkage, and with transportation wheels). Ford TW tractors would be up there too, but there's no chance of a license for those.
Plenty of farms still use old equipment.
On the farm I used to work on there is an old Massey Ferguson 135 from the 60s. I used to lead bales with it, and it's still going now, though needs a bump start to get going as the starter motor has gone... but it's the only tractor of theirs which will fit in an old shed so it can be mucked out.
