So looking on CDKEYS, I can see 4 main base games:
Euro Truck Simulator 2
Euro Truck Simulator 2 Gold
Euro Truck Simulator 2 GOTY
Euro Truck Simulator 2 Legendary Edition
The price range is £5.99 up to £9.79 so obviously the cost isn't an issue.
Is there any oddball reason not to go for the Legendary Edition?
I'd get the legendary for: Going Eeast, Scandinavia, High Power Cargo, assuming that comes in cheaper than direct from steam. Map DLC is typicaly about £4 each on steam. (its worth comparing, as prices change and bundle offers change)
Also High power cargo, Special transport and Heavy cargo packs are £1.20 each at the moment on steam, so i think i might be also tempted to grab Special transport and Heavy cargo for an additional £2.40.
It's all about working out wich package gives you the most..the Map DLCs and the cargo DLCs are worth having, paint job packs are pretty worthless IMO, so i'd not care what combo of them came with a bundle.
