This paper describes the initial stages of a project which seeks to develop a language learning game for Italian running a deep linguistic grammar at its backend for fine-grained error detection. The grammar is designed within the grammatical framework of Lexical Functional Grammar (LFG). The project aims to bring together work from different fields by combining strategies from computational linguistics with theoretical insights from Second Language Acquisition (SLA) and components from computer gaming.
