Art style, fidelity, and realism are all somewhat separate. Yeah a good art style can make a game timeless. There are countless examples of that. But it doesnt mean that realistic looking games cant have a great art style. I think cohesion is a huge part of what people mean by "art style". Realistic looking games that focus on having a cohesive look can also be fairly timeless. They may not compete with today's fidelity (resolution, technology, etc), but Assassin's Creed, various Battlefield games, Crysis 1, and plenty more all look great if you look at them today.
Theres also the concept of somwthing not realistic, but high fidelity. Minecraft RTX is simply amazing. Taking that already timeless art style and increasing the fidelity doesn't suddenly remove the timeless factor, and i love that. I want more of that. Even if it means i need a fairly beefy gpu for such simple graphics otherwise.
Doesn't mean we call them heros and erect monuments to them. if anything we place these objects in a museum dedicated to the group. We acknowledge their troubled past, difficult decisions, horrible actions, good actions, and learn from all of it. A sense of shame and humility doesnt make current Ukrainians bad in any way.
