BBC Micro Elite: black and white view, yellow, red and green instruments, maybe 640x512 resolution. Great game.
Archimedes Chocks Away: plain single-colour polygons, simple models, flat single-colour "landscape", plain blue sky, no sun, shadows straight down, cluster of red, yellow and black polygons for an explosion. Great game.
Early PC up to Win XP original Doom II: five sprites and the reflections of three of them for your opponents, no shadows, nothing sloping, nothing sliding or swinging, no spray or mist effects, no ragdoll. Great game.
Any platfrom, load of shit: 2560x2048 resolution in four billion colours, full ragdoll effects including severed limbs, real-time rayshading, realistic weather with frontal systems, grass that sways in the wind, bees that actually visit flowers and track which ones have been recently visited so they only go to the ones with plenty of nectar, fifty different species of songbird mapped to half-millimetre detail, twenty different stone textures for each region to make the buildings more realistic, persistent brass and wood chips, plants that slowly, realistically recover after vehicle damage, flocks of sheep that will escape from fields if you leave the gates open and can break headlights, an ocean with waves that actually knock you down if they're big, real-time raytracing applied to the sea surface too, tides, tidal currents faithfully mapped from real world charts, freshwater and seawater density differences used to calculate mixing patterns and turbulence, sediment load tracking, iron mine tailing heaps that interfere with your in-game compass, insect build-up on your windscreen in rural areas and over two hundred different voice sample sets used for your AI team-mates. Still a shit game.
