The date locations/activities I choose depends on what suits the couple. My main couple sometimes just like to have a cosy night in at home. One usually cooks a nice meal for them to eat together, then they might cuddle up to watch a film or dance together, before taking things upstairs to the bedroom. My main sim's partner actually 'surprised' him with a romantic meal at home before proposing to him during a date, which was perfect. When out on dates, they sometimes dine out at restaurants, go for drinks and listen to live music at bars/lounges, view/discuss artefacts at museums, sit together at the park or romantic garden snuggling by the fountain or looking up at the stars/clouds etc. I am a hopeless romantic so I really like to make sure my couples spend quality time together and I would love to see the romance system developed further to include more romance interactions and possibilities for dates.
