Impressions Software was a UK software development house founded in 1989 by David Lester. Its focus was on strategy and business games, including sports-team management simulations. It also experimented with edutainment (Project USA) and casual software (Casino Deluxe). With a stable of partners and freelancers, including Edward Grabowski and Simon Bradbury, the company grew into a stable, successful studio. Impressions was bought by Sierra On-Line in 1995.
