The Commodore VIC-20, Commodore’s first attempt at a budget color home computer, often gets lets out of the spotlight in favor of its more capable successor, the Commodore 64. Back at release it had significantly limited RAM even for the time, only 5K, and it also had only eight colors for general use, simple sound, and no hardware sprites. Even so, it did all right in the market, but was quickly overshadowed by Commodore’s more powerful followup.
But all of these factors mean that making substantial games for it is both a more interesting challenge, and a lot more impressive when it’s done well. Youtube channel RetroGamerNation did a roundup video of interesting VIC games made in 2022. Remember, when watching these videos, the VIC had no sprites. I personally like the look of Flood. Most of these games require significant RAM expansion to run (on the VIC-20, “significant” means at least 16 kilobytes), but many people who try them out will be running them on an emulator anyway, and one of the games actually runs on an unexpanded VIC.
