Video games play fast and loose with realism by definition, but authenticity still matters to some degree After all, it's hard to enjoy a history-focused game if there are obvious factual errors. So how does Battlefield 1 stack up, then? So far so good, if you ask the World War I history buffs at The Great War. They've conducted a shot-by-shot breakdown of the cinematic trailer and revealed that EA DICE is largely faithful to the technology of the conflict -- including in ways you wouldn't expect. That shovel-wielding German soldier you see above makes sense, for example, as the infantry learned that bayonets got stuck in victims. Early tanks behave as they should, and things like gas masks or pickaxes (for Italian soldiers scaling mountains) are true to form.
